Desktop Environments Resource Usage Comparison

Some of them use more RAM. Some less. Today in a rather simplified benchmark I will check some popular desktop environments for their RAM usage. I recently came to see some more or less old comparisons of various desktop environments RAM usage.

They were focused on difference between XFCE and KDE/Plasma environments. I am used to idea that XFCE is smaller and lighter of the two – so it should be also lighter on resources – but these two movies state that they RAM usage is similar and sometimes even KDE/Plasma is lighter. These results seemed strange to me so I wanted to test them under latest FreeBSD 13.1-RELEASE UNIX system.

Example XFCE on FreeBSD desktop screenshot from the XFCE Cupertino Way article.

xfce-ghostbsd

Upon some popular demand I also added GNOME (the 42 version) to the comparison.

Today we will test these desktop environments:

  • XFCE (4.16)
  • MATE (1.26)
  • KDE/Plasma (5.24)
  • Openbox (3.6)
  • GNOME (42)

We all know that Openbox is just a window manager but I wanted to include it here just from comparison.

Test Environment and Process

To save time I used VirtualBox virtual machine for the purpose of these simplified benchmarks. For that purpose he created VM had:

  • 1 x CPU
  • 8 GB RAM
  • 128 MB GPU Memory
  • 30 GB Disk

After installing the vanilla FreeBSD 13.1-RELEASE I switched to the latest pkg(8) repository. Then I added needed packages:

# pkg install xorg xfce kde5 mate openbox dzen2 tint2 xbindkeys xterm geany gnome

All of the desktop environments and their dependencies were installed on that test machine. The main FreeBSD config at /etc/rc.conf file had following contents.

% cat /etc/rc.conf
hostname="freebsd"
ifconfig_em0="DHCP"
sshd_enable="YES"
moused_enable="YES"
powerd_enable="YES"
dumpdev="AUTO"
zfs_enable="YES"
dbus_enable="YES"

The only thing I added after installation was the dbus service startup. I did not changed any settings in these environments. The were compared at their default settings.

The test was rather simple and naive but these were the tasks that I done on each of them.

  • Run gstat(8) command in terminal application.
  • Display /etc/ in file manager with scroll to end of display of dir.
  • Open /etc/ssh/moduli file in text editor with scroll to end of file.

These were different for various environments:

XFCE

  • xfce4-terminal
  • thunar
  • mousepad

MATE

  • mate-terminal
  • caja
  • pluma

KDE/Plasma

  • konsole
  • dolphin
  • kate

Openbox

  • xterm
  • caja
  • geany

GNOME

  • gnome-terminal
  • nautilus
  • gedit

I powered off that FreeBSD machine before each test – so each test looked like:

  • boot cold FreeBSD system
  • login into system (in text console)
  • type xinit(1) command
  • do the 3 defined tasks

Each desktop environment had different ~/.xinitrc file. Below you will find their contents.

% cat ~/.xinitrc.xfce
. /usr/local/etc/xdg/xfce4/xinitrc

% cat ~/.xinitrc.mate
exec ck-launch-session mate-session

% cat ~/.xinitrc.kde
exec ck-launch-session startplasma-x11

% cat ~/.xinitrc.openbox
dzen2 &
tint2 &
xbindkeys &
exec openbox

% cat ~/.xinitrc.gnome
exec gnome-session

Each of them were started like that:

% xinit ~/.xinitrc.xfce

% xinit ~/.xinitrc.mate

% xinit ~/.xinitrc.kde

% xinit ~/.xinitrc.openbox

% xinit ~/.xinitrc.gnome

RAM Usage Results

To be honest I was surprised by the results.

Clean Text Console FreeBSD

The text console of FreeBSD 13.1-RELEASE system used about 97 MB of RAM. That result is the sum of the RES column from the top(1) command.

Below you will find the top(1) output for FreeBSD text console only system.

MATE

Next one is MATE and it used about 1361 MB of RAM.

This is first strange thing for me. Keep in mind that MATE is a fork of GNOME 2 which was expected to be heavy compared to light XFCE … at least more then a decade ago. Seems that now MATE developers are doing better job then XFCE devs πŸ™‚

Below you will find the top(1) output for MATE.

KDE/Plasma

Next one is KDE/Plasma and without surprise (at least for me) it uses more RAM then other desktop environments – about 2843 MB of RAM – that is more then twice as much as MATE and almost twice as much as XFCE.

Below you will find the top(1) output for KDE/Plasma.

Summary of the RAM usage results are below.

CPU Time Usage Results

As I already had the top(1) outputs I also compared the CPU time used for that limited test. I will not post the top(1) results again as they are posted above. The Seconds column below is the sum of the TIME field from the top(1) command output.
Here are the results of used CPU time.

SECONDS  ENVIRONMENT
-------  --------------------
      0  FreeBSD Text Console
      7  Openbox
     26  MATE
     42  XFCE
     72  GNOME
     92  KDE/Plasma

Seems that MATE is twice as light on resources then XFCE. World has changed a lot since GNOME 2 was considered heavy fully fledged desktop environment while XFCE was light and fast … but even that ‘hungry’ XFCE takes only half of the time that KDE/Plasma uses for the same tasks.

Subjective Experience

The Openbox ‘environment’ started fastest and was most responsive to operate.

Both MATE and XFCE started little slower but after they loaded the desktop and taskbars they were snappy and fast to use.

On the other hand the KDE/Plasma took longest to load and each application I started – I needed to wait ‘a little’ with ‘bouncing mouse cursor’ for them to load. Also scrolling the /etc/ssh/moduli file to its end in Kate took REALLY long … even with Logitech M720 mouse which scroll wheel was spinning freely (without clicks). I want to mention that I am not disappointed by KDE/Plasma. Its just slower when used in a limiter 1 CPU and 8 GB RAM environment. Probably the load times and usability is a lot better on a 4 CORE system with 16 GB of RAM on fast NVMe SSD disk while we used rather slow virtual machine.

After adding GNOME to comparison it felt even slower then KDE/Plasma. Probably because GNOME requires hardware 3D acceleration for smooth operation. With its software rendering it felt really sluggish … while consuming less RAM and CPU time then KDE/Plasma.

Summary

Not sure how useful that is but I just was curious and wanted to check it out – and as I did I share what I found.

UPDATE 1 – Added freecolor(1) and htop(1) RAM Measurements

After suggestions from other places I added freecolor(1) and htop(1) measurements when it comes to RAM usage. Here are the results.

            | htop(1) | conky(1) | freecolor(1)
    FreeBSD |  112 MB |    - -   |  157 MB 
    Openbox |  237 MB |  460 MB  |  382 MB 
       MATE |  508 MB |  778 MB  |  788 MB 
       XFCE |  533 MB |  794 MB  |  829 MB 
helloSystem |  585 MB |    - -   |  830 MB 
      GNOME |  625 MB |  990 MB  | 1000 MB 
     Plasma |  730 MB | 1659 MB  | 1167 MB

Hope that helps.

FreeBSD 13.1 on ThinkPad W520

I created whole FreeBSD Desktop series … but I never created an article describing how I run FreeBSD on my own daily driver – the Lenovo ThinkPad W520 from 2011 – the last one with the so much appreciated 7-row keyboard. In this article I will share how I configured FreeBSD to make the most of it. If you are curious why I use such old laptop then my older Epitaph to Laptops article explains that in detail.

This is the Table of Contents for this article.

ThinkPad W520

This machine was out-fucking-standing when it was released in 2011 … and expensive as hell also πŸ™‚ With 4 physical cores and up to 32 GB RAM only a few laptops could compete with it – Dell Precision M4600 – also could do that back then … but not exactly the same. You see – the last Dell Precision to carry similar 7-row keyboard was Dell Precision M4500 – but that one was from 2010 and was able to pack only … 8 GB RAM (official) and 16 GB RAM (unofficial) – so its not a fair comparison. Today 11 years (!) later ThinkPad W520 is still very capable and powerful machine. The only thing that you may need to do is to replace the thermal paste. I also did that – Classic ThinkPad Thermal Paste Change – as described here.

0THIS-w520-freebsd

To make you imagine how big that 11 years time span in IT is I will try to show you example with a car. Its like driving 30 years old Mercedes-Benz W124 from 1992 today because IT world and hardware changes and improves a lot faster then automobile industry. The Mercedes-Benz W124 with its indestructible automatic transmission and engine along with comfortable suspension and automatic air conditioning – offers daily experience not that far away from today’s cars – the meritum is definitely fulfilled. I know that from first hand since I owned one not that long ago. Not to mention its legendary reliability. Its also a car that is very liked by mechanics as its very ‘serviceable’ and has lots of space for everything. You do not need to disassemble entire front bumper and the headlight just to replace a broken light beam.

w520.mercedes.w124

This is the same that I would say about ThinkPad W520 today. You can put three (!) storage devices at the same time. Two 2.5 SATA drives and one mSATA disk. Assuming you would use 8 TB 2.5 Samsung QVO drives and 2 TB mSATA drive you would have 18 TB of storage … in a 11 years old laptop. You can grow that to 19TB with 1TB SD card in the slot … and we even did not touched any USB ports yet. Today you are able to get ThinkPad W520 in nice condition for about $300 if you are not heisty and getting 32 GB of DDR3 RAM costs another $100 so its pretty affordable hardware.

Specifications

For the record below You will find specs of mine machine. I also added driver and/or package that is used to support these devices.

CPU: Intel Core i7-2820QM 2.30GHz (4C/8T) Sandy Bridge 32nm
RAM: 32 GB (4 * 8GB DDR3)
HDD0: 128GB mSATA Samsung PM830 (system)
HDD1: 4 TB 2.5 SATA Samsung 860 QVO (data)
GFX0: Intel HD Graphics 3000 (integrated) [graphics/drm-kmod]
GFX1: Nvidia Quadro 2000M (discrete) [x11/nvidia-driver-390] {nvidia}
SCR: 15.6 1920x1080
USB: 2 x USB 2.0 + 2 x USB 3.0 [ehci(4) + xhci(4)]
AUDIO: Conexant CX20590 [snd_hda(4)]
PORTS0: 1 x VGA
PORTS1: 1 x DisplayPort
PORTS2: 1 x eSata
SD: Card Reader 5in1 [sdhci(4)]
LAN: 10/100/1000 Intel 82579LM Gigabit [em(4)]
WIFI: Intel Centrino Ultimate-N 6300 AGN 802.11n [iwn(4)]
BT: Bluetooth 3.0 [ng_ubt(4)]
CAM: Webcam 720p [multimedia/webcamd]

Articles such as this one often focuses on what works and is supported by FreeBSD and what is problematic or does not work at all. The very nice thing about ThinkPad W520 under FreeBSD command is that EVERYTHING works. From Bluetooth through Card Reader and also multiple suspend/resume cycles. I am doing months of uptime on that laptop and I reboot only when I need to update the system or I want to test something … but that often also does not need reboot now as you can just reroot into other BE as described in my other ZFS Boot Environments Revolutions article.

I do not need the compute power of discrete Nvidia Quadro 2000M card so I disabled it in the BIOS – but when I tried it with drivers from the FreeBSD Ports – everything worked as desired. I use integrated Intel HD Graphics 3000 which is more then enough for my needs. To be honest I would get ThinkPad T520 which can be bought with integrated graphics only but it has two downsides. The T520 does not have any USB 3.0 ports – that one I could probably live with but … it comes only with Dual Core CPUs. You can of course place a Quad Core CPU in it by yourself – but as W520 exist I do not see a reason not to get one πŸ™‚

FreeBSD System Configuration

From many things that I really like about FreeBSD (more here – Quare FreeBSD? – in separate article) is that it can be mostly configured using just 3 files. This configuration already features all power management settings that I described in the The Power to Serve – FreeBSD Power Management article.

I installed FreeBSD in a pretty standard way with GELI full disk encryption enabled and with ZFS as the filesystem as I can not live without ZFS Boot Environments. The FreeBSD installer automatically detects and applies the so called ‘Lenovo Fix‘. When in doubt the installation procedure is described in the FreeBSD Desktop – Part 2.1 – Install FreeBSD 12 article.

Main FreeBSD configuration files.

  • /etc/rc.conf – system and services configuration
  • /etc/sysctl.conf – runtime parameters configuration
  • /boot/loader.conf – parameters configurable at boot

I will also include these below as they are also important:

  • /etc/devfs.rules – devices configuration
  • /etc/fstab – filesystems configuration
  • /etc/ttys – terminal initialization configuration
  • /etc/wpa_supplicant.conf – WiFi configuration
  • /usr/local/etc/automount.confautomount(8) configuration
  • /usr/local/etc/doas.confdoas(1) configuration
  • id(1) groups membership
  • /usr/local/etc/X11/xorg.conf.d/* – X11 configuration

First the main /etc/rc.conf configuration file.

Wireless config – as an example for different network types. As you have seen I did not included any network information in the /etc/rc.conf file – this is because I use my own network.sh solution to connect to various both wire and wireless networks – FreeBSD Network Management with network.sh Script – described in detail here.

Desktop Environment

Openbox

As for the ‘desktop environment’ that I use – its my custom setup with Openbox along with tools like Tint2 and Dzen2 – for the most basic setup. The screenshot is from FreeBSD 11.1 but it looks exactly the same today.

freebsd-desktop-2019-04

I described this setup in details in the entire FreeBSD Desktop series.

XFCE

I have also tried XFCE – I liked it especially with the Global Menu app-menu plugin. You go this way with this XFCE Cupertino Way handy guide.

xfce-ghostbsd

GNOME

I also tried GNOME for a test – it did not suit me well so I went back to my Openbox setup – but You may find it more comfortable to use. Here is the FreeBSD GNOME 3 Fast Track article that will help you with that.

Accessories

There are some accessories that are very handy with the ThinkPad W520 laptop. I will describe them below.

Smaller Power Supply

The ThinkPad W520 comes with quite large brick of ThinkPad 170W Power Supply. It works. Its OK … but you can use smaller one and more universal at the same time. I use the ThinkPad 135W Power Supply that originally was sold with ThinkPad W510 – the earlier model. Besides being smaller in size it also has one additional advantage. Its plug is round and also fits into other ThinkPads from this line like ThinkPad X220 or ThinkPad T420s. The original ThinkPad 170W Power Supply unfortunately only fits into the ThinkPad W520 laptop. Below you can compare their sizes.

w520.ps

Mouse Companion

After checking many mouse models – as described in the UNIX Mouse Shootout article – I finally settled with Logitech Triathlon M720 mouse. I have plugged the Lenovo USB Receiver into the back ‘powered’ USB port. While I use that mouse over the USB receiver you can also connect it using Bluetooth – also to other computers. This mouse has a special dedicated button to switch between 3 different computers. Unfortunately the copy-paste between them does not work πŸ™‚

mouse-M720

If you would like to ‘save’ that port for something else then you may use special USB board adapter that you will place in the Bluetooth module under the palm rest. You would loose Bluetooth support then of course – but not everyone uses that. Its available for example on Aliexpress site and looks like that.

w520.usb-bluetooth-pink

I do not use it as I do not need the ‘back’ USB port so below you will find its mounted picture on the ThinkPad X220 laptop instead – along with the Lenovo USB Receiver attached.

w520.usb-bluetooth

Two Additional USB 3.0 Ports

The ThinkPad W520 comes with not well known today ExpressCard port. With this cheap adapter from Aliexpress you can add two additional USB 3.0 ports. You may of course do not need that many ports – but if you are left handed then you probably use mouse on the left of your laptop – then USB ports on the right will be handy.

w520.express

These USB 3.0 ports may be also useful with some bhyve(8) setups. Currently its not supported to pass-thru just a single USB port to a virtual machine. You need to pass thru entire controller. This way you can pass-thru that controller to bhyve(8) VM and have another USB 3.0 ports on the host.

Larger Custom Battery

The original largest extended battery for ThinkPad W520 had 9400mAh capacity. Its possible to get even larger custom extended battery but in the same physical size and shape – with 9600mAh capacity – and for only about $50. To remind you the original one costs closer to $200 unfortunately. I got mine from this Aliexpress page. With my power settings and with this battery along with enabled WiFi and screen brightness just one step less then maximum brightness it show more then 7 hours of time left in acpiconf(8) command.

% acpiconf -i 0
Design capacity:        10368 mAh

As you can see from the command above this custom battery size is even reported as closer to 10400mAh instead of advertised 9600maH. I do not know how to check which one is closer to truth – but the fact is that it allows longer work then the official one – and for smaller price.

Experience

This laptop along with its smaller and lighter brothers such as ThinkPad X220 or ThinkPad T420s are the best machines I know to work on FreeBSD … but maybe its because I do not use newer laptops πŸ™‚ The general experience of FreeBSD on ThinkPad W520 is stable and uninterrupted work count in days and weeks of uptime. The suspend/resume works like a charm with many cycles possible – not just one. I one even recorded such suspend/resume cycle with many applications and games running on a busy FreeBSD system. Its available here FreeBSD 12.2 Suspend/Resume on a Vimeo page.

Here is now its being used daily.

w520.real

Summary

I have been using this laptop since many years and I even laugh that as its a decade old – I would use it for the next decade πŸ™‚ Most/all of this configuration applies to other ThinkPad models from this lineup like X220/T420s/T420/T520 … probably even L520 (but I did not tested that one).

XFCE Cupertino Way

I really like GhostBSD … and NomadBSD. They are really great graphical and easy to use FreeBSD variants for the lack of better word. While NomadBSD is more focused on portable USB pendrive edition the GhostBSD is more like a Ubuntu replacement. Install and use on your laptop or desktop computer. It comes in two flavors – the default MATE edition and an alternative XFCE edition.

One of the things I really like about Ubuntu MATE edition is that it comes with desktop layout helper tool that will allow you to select one of the available predefined MATE desktop layouts.

ubuntu-mate-desktop-layout

From all of the available ones I like the ‘Cupertino’ one the most – its tries to mimic the Apple Mac OS X operating system behavior with global menu on top and Plank dock at the bottom … and it does it really well.

ubuntu-mate-cupertino

I wanted to do something similar on GhostBSD but unfortunately the Vala Panel Application Menu for MATE desktop environment is not available for FreeBSD (and that means its also not available for GhostBSD). Fortunately the XFCE global menu is available on FreeBSD as x11/xfce4-appmenu-plugin package so I will try to make GhostBSD look more like Ubuntu Mate in its Cupertino layout with several easy steps.

By default GhostBSD XFCE edition comes with single XFCE panel at the bottom. I have done pretty straightforward installation with fish(1) shell chosen as default during installation.

ghostbsd-xfce-default

Fonts

By default GhostBSD comes with 96 DPI set by the installer. Lets change that to something smaller. Start the Appearance application.

xfce-appearance

Now set the desired settings for the fonts on the Fonts tab. After some checks the 80 DPI along with Hinting set to None looked best. I also switched to the Ubuntu font.

xfce-fonts

ZSH Shell and Terminal

While the fish(1) shell is quite decent interactive shell with sane defaults I really prefer the POSIX syntax compatible zsh(1) shell instead. I talked more about that in my Ghost in the Shell – Part 7 – ZSH Setup article.

I will not repeat everything I wrote there and I will just paste the instructions here to make that zsh(1) shell configured and nice looking.

root # pkg install -y \
         zsh \
         zsh-autosuggestions \
         zsh-syntax-highlighting \
         ubuntu-font

root # fetch -o /usr/local/etc/zshrc https://raw.githubusercontent.com/vermaden/scripts/master/zshrc

user % fetch -o ~/.zshrc             https://raw.githubusercontent.com/vermaden/scripts/master/DOT.zshrc

user % fetch -o ~/.zshrc.DOAS.SUDO   https://raw.githubusercontent.com/vermaden/scripts/master/DOT.zshrc.DOAS.SUDO

user % chsh -s /usr/local/bin/zsh

user % fc-cache -f

As we are at the terminal related things enable Solarized (Dark) theme in the XFCE Terminal options.

terminal-theme

… and change font to Ubuntu Mono with your preferred size.

teminal-font

Now you have the zsh(1) shell configured and set as your default shell. Also the XFCE Terminal looks better now. Some settings will require logout and login route but I recommend something different. Go through all these setting and then do just one single reboot or logout/login routing.

zsh-ready

XFCE Global Menu

I though that XFCE global menu is – same as MATE one – not available on FreeBSD. Fortunately Joel Carnat with its FreeBSD 13 on ThinkPad T460s article proved me wrong. He even added the instructions to his guide – for which I am very thankful to him.

To get XFCE global menu on FreeBSD (and GhostBSD) we need to do these steps.

root # pkg install -y xfce4-appmenu-plugin

user % xfconf-query -c xsettings -p /Gtk/ShellShowsMenubar -n -t bool -s true

user % xfconf-query -c xsettings -p /Gtk/ShellShowsAppmenu -n -t bool -s true

user % xfconf-query -c xsettings -p /Gtk/Modules -n -t string -s appmenu-gtk-module

Now we will be able to add the XFCE AppMenu Plugin to our top panel.

xfce-appmenu-plugin

We need to now move the XFCE panel from bottom to the top. Go into the Panel Preferences as shown below and move it.

xfce-panel-move-top

After moving it to the top and enabling the Lock Panel option add/remove the Items to match this list below. Feel free to also add other items that you need.

xfce-top-panel-items

To make the XFCE AppMenu Plugin look even better enable Bold Application Name in its Preferences dialog.

xfce-appmenu-bold

As for the Whisker Menu left only icon enabled to display to make it look better.

whisker-icon

The XFCE AppMenu Plugin should be now ready and the top panel should look somewhat like that.

xfce-global-menu-short

You can also customize the DateTime plugin to your needs.

xfce-datetime

Window Manager

The Window Manager settings are not controlled by the Appearance application. It has its own separate one. Lets start it.

xfce-window-manager

We will also set the Ubuntu font here.

Groups

Make sure your user (vuk in this guide) is in below groups.

root # pw groupmod wheel    -m vuk
root # pw groupmod operator -m vuk
root # pw groupmod video    -m vuk
root # pw groupmod network  -m vuk

You can omit the network group if you do not intend to use network.sh to manage your network connections.

Plank

As the last step we will add the Plank dock at the bottom.

root # pkg install -y plank

user % plank &

user % plank --preferences

You should see something like that on the bottom of your screen.

xfce-plank-bottom

The Plank preferences are shown below.

xfce-plank-preferences

Make sure to add Plank to Startup so it will start automatically at each login.

xfce-plank-startup

Result

After all these steps our GhostBSD looks more or less like that now.

xfce-ghostbsd

Plain FreeBSD Way

Some people will prefer to stick to the ‘original’ FreeBSD instead of using preconfigured GhostBSD. This last section is for them. First install FreeBSD like described HERE. Then install these packages shown below.

root # pkg install -y exa ubuntu-font xfce xfce4-appmenu-plugin xorg-minimal

user % echo '. /usr/local/etc/xdg/xfce4/xinitrc' > ~/.xinitrc

user % xintrc

Now having done the above do all the steps from that article.

The end result seems quite similar.

xfce-freebsd

You may even want to replace Plank with another bottom XFCE Panel if you want.

xfce-freebsd-pkg-prime

Viola! You have XFCE configured on plain FreeBSD. One thing to keep in mind is that besides XFCE you have nothing more πŸ™‚ Using GhostBSD method all other things are configured. With plain FreeBSD way you have no device automounting. No network plugin in the taskbar. No power management tuning. No other applications. Nothing. But you can all do it yourself using the needed articles from the FreeBSD Desktop series or other sources.

One last thing. I really appreciate that GhostBSD exists and is actively maintained and expanded – this guide is not here to make it look bad. Its here to make it better.

Regards.

Epitaph to Laptops

This article was in my ‘TODO’ list since almost start of this blog several years ago. Usually I try to focus on positive side of things but this article is one way highway quite the opposite way. If you do not want do lose your good attitude then please do not read further. Nothing good awaits you at the end for you unfortunately. The song of King Crimson – Epitaph is appropriate tune here. You have been warned.

Naive

When I was younger I though that World only gets better. Things are improved. People live better and longer. Cars broke less frequently and need less maintenance. Computers not only go faster and draw less power but they become more usable and allow people to be more productive because of new features introduced.

Unfortunately it’s not true. Some things are improving but other get forgotten or get worse. Depending on the current geopolitical situation people live better or worse. Cars are more complicated then ever so they broke more and are now also often disturbed by software and firmware updates – not to mention bugs and security issues. It’s harder today to find a car (even used one) that is reliable, cheap in maintenance and also with engine not crippled by for example EURO 7 regulations enforced by EU. Computers are faster … or at least they have more CPU cores and draw some less power but one thing in computing went entirely wrong way.

Laptops

It’s not about their CPUs or RAM. Screens also got better – they are brighter then ever – and FullHD 1920×1080 resolution finally become the standard. Some manufacturers went even further with 16:10 or even 3:2 screen ratios. Larger touchpads with support for multi touch and gestures are also very often and welcome. There is however one aspect that ALL laptop manufacturers got entirely wrong.

Keyboards

The first laptop I got was Dell Latitude C600.

0THIS-dell-c600-mod-freebsd

With its 7-row keyboard and functional INS/DEL HOME/END PGUP/PGDN layout at the top right side probably fixed me for life.

0THIS-dell-c600-keyboard

This is the most important fragment I am talking about.

0THIS-INS-DEL

It was so obvious for me that it was there – providing standard cursor position manipulation without taking all the space that a TKL (tenkeyless) keyboard takes. Its 1024×768 screen resolution may seem very ancient today but it was higher then the default consensus at 800×600 one back then.

Besides the great keyboard that Dell laptop also provided other useful feature – modularity. It had two universal bays for things like:

  • batteries
  • CD-ROM or CD-RW drive
  • floppy drive

You could put two batteries to maximize battery power or put CD-RW drive instead of battery to get other functionality. The two batteries also meant that you could run this laptop as long as you want if you only had enough charged batteries. This was available almost two decades ago. 19 years to be precise. My currently favorite FreeBSD operating system also run well on it with Fluxbox on X11 display server.

In that time many laptop manufacturers provided both more productive 7-row keyboard and modularity … or at least business oriented ones … even with SUN SPARC or IBM POWER CPUs. The IBM RS-6000 POWERbook is shown below.

0THIS-IBM-RS-6000-601

… and the Tadpole SPARCbook also.

0THIS-Tadpole-SPARCbook

Several years later I went for upgrade and got the Dell Latitude D630 laptop with successful Intel Core 2 Duo CPU and 1400×900 screen which provided so much more screen space and flexibility.

0THIS-dell-d630-freebsd

Besides the obvious 7-row keyboard its creators got great idea that extended main battery would extend in the front of the laptop instead of the back. That had two implications. First – you got a lot of usable ports at the back. Second – you got additional elegant palm rest on the front. Both Dell D630 batteries shown below.

0THIS-dell-d630-battery

Besides this ‘frontal’ idea it also had universal UltraBay slot on the side which similarly to the earlier Dell C600 allowed one of the following accessories:

  • CD-RW or DVD-RW drive
  • additional bay battery

Thanks to that you could extend the battery life of your laptop to about 8 hours … even on FreeBSD with its limited power management back then. You could also get additional batteries to work as long as you like of course. It was introduced in 2007. I even run OpenSolaris on that laptop for some time and all hardware was fully supported. The only problem OpenSolaris had back then is the same one as OpenIndiana has now. Very small amount of packages of additional software. Back then FreeBSD provided most software that was available on Linux but OpenSolaris was in its own limited league. I really liked OpenSolaris WiFi management with dladm(1M) tho.

After some time my attention went into revolutionary Lenovo ThinkPad X300 with custom low power Core 2 Duo L7100 CPU designed by Intel only for this model.

0THIS-thinkpad-x300

It was as thin and light as Apple MacBook Air while providing same functionality and modularity as other Latitude and ThinkPad laptops. Same as my previous laptop it had ‘main’ and ‘additional’ battery interchangeable with the DVD-RW drive. It had awesome speakers. Never had THAT GOOD speakers in laptop again as they were ThinkPad X300.

After I started my work at new employer I got Dell Latitude E6400 so Lenovo ThinkPad X300 became kinda redundant.

0THIS-dell-e6400-freebsd

That Dell was NOT as sturdy or reliable as magnesium body Dell D630 but it had the most important feature – the oldschool 7-row keyboard.

Life went by and some time later I needed to take a look at something newer. At my work I got myself in the position of being responsible for selection of a laptop that would be successor for the Dell Latitude E6400 that we had. After checking what is available I frighted for Lenovo ThinkPad W520 back then … and I even succeeded … and failed at the same time.

0THIS-task-failed

I got approval for my choice for entire department … but the corporate process to make it happening took so long that Lenovo stopped offering ThinkPad W520 and started shipping its successor ThinkPad W530. I was really sad by that fact – the ThinkPad W530 was the first Lenovo laptop with new ‘island’ type keyboard instead of the classic 7-row keyboard.

0THIS-thinkpad-w530-freebsd

The so much appreciated and needed INS/DEL HOME/END PGUP/PGDN block was gone … forever. I thought that maybe the World is ‘right’ and I am ‘wrong’. For the next 3 years I have tried to ‘migrate’ mentally with my ‘muscle memory’ to the new island keyboard layout … unsuccessfully. The only thing that went well was … ThinkPad W530 warranty keyboard replacement because the key with letter ‘E’ failed and fell off.

It was obvious for me that I need to get other laptop – a one with 7-row keyboard layout. Today I would probably just reflash the ThinkPad W530 Embedded Controller with custom firmware written by Hamish Coleman and put there ThinkPad W520 keyboard there but that option was not available back then. I also encourage you to watch the Hamish Coleman speech My Personal Fight Against the Modern Laptop from 2017.

After checking what laptops the World has to offer … I was disappointed. Since 2012 not a single laptop manufacturer offered a laptop with 7-row keyboard. Zero. Nada. Zip. None. I decided to take a look in the past instead. The last Dell Latitude models that got the 7-row keyboard were E6410 for 14″ or 6510 for 15″ screen – were introduced in 2010. Lenovo with its X220/T420/T420s/T520/W520 lineup were from 2011 – survived a year longer. As I got used to 14 inches I opted for ThinkPad T420s (slimmer and lighter ThinkPad T420 version).

0THIS-T420s

With its 1600×900 screen and also my usual two batteries setup (with one being placed in the UltraBay) It was pleasure to use (and carry as it was quite light also).

In the mean time it was needed for me to pick up newer laptop at my employee. Knowing what market has to offer I only wanted the laptop to be light and small and that it should have FullHD 1920×1080 resolution screen … and my demands were met. I got Dell Latitude E7280 laptop … with GLARE touch capable FullHD screen. Great …

0THIS-dell-E7280-laptop

As you can see it was running Windows and my ex-company policy was very simple here. Windows or GTFO. For the first several years – when my ex-company was not that big I was able to work more productive with FreeBSD on that ThinkPad W530. Unfortunately that ex-employer grown to the ‘corporation’ level too much and that ruined many things. After having ThinkPad W530 I did not expected much from new Dell but it got my disappointment to a whole new level. Take a look at the top right part of its keyboard.

0THIS-dell-E7280-keyboard

Besides the fact that INSERT key is ‘shared under the F12 button and I need to use now the FN key to send it each time is another level of PITA … but placing the keyboard shortcut to DISABLE WIFI one key next really got me pissed. I do not have to tell you how many times instead if just pressing INSERT key I disconnected my WiFi card which also meant disconnecting VPN and all the tasks that I had in place … not to mention how much time it takes to first reconnect WiFi and then to reconnect again to the VPN … but the next key to the right is SUSPEND – which I also got several times while only trying to use INSERT. Awesome. Even better. Also – did you notice where is the POWER button? Yes – I also lost part of my work several times because of that. Probably Dell Latitude E7280 was my worst laptop experience.

Some may wonder why I use INSERT so much? I got used to copy-paste with SHIFT-INSERT and CTRL-SHIFT-INSERT shortcuts – this is the guilty one I suppose.

Some time later – as size and weight was not an issue – the larger FullHD 1920×1080 screen equipped ThinkPad T520 laptop got my attention. I did not needed the dedicated graphics card of ThinkPad W520 but there were two drawbacks comparing to ThinkPad W520. Four physical CPU cores and USB 3.0 ports. With current JavaScript overblown web pages World I welcome the fact that ThinkPad W520 can hold 32 GB of RAM. It was huge amount in 2011 when it was released and it is more then enough now. As you probably guessed I got the ThinkPad W520 laptop.

0THIS-w520-freebsd

It was the best upgrade ever. After replacing the thermal paste as described in my older Classic ThinkPad Thermal Paste Change article I finally felt like at home again. Its not possible to add additional battery into the UltraBay slot as only DVD-RW or SATA HDD caddy are allowed – but with extended battery I get about 5+ hours of battery time – more then needed.

Fast forward to today … I am running 11 years old ThinkPad W520 laptop and looking at what is available – I do not see any perspectives on what could be my next daily driver. All manufacturers decided to abandon the productive 7-row keyboard in order to sell ‘island’ type keyboard equipped laptops. Some of them even went completely insane as they now add a POWER button on the top right keyboard key. Insanity.

0THIS-POWER-button

The only thing a reasonable user can do is to disable it in the software to not accidentally lost its work.

For some time I believed that Lenovo would make something more from its Retro ThinkPad initiative that allowed ThinkPad 25th Anniversary Edition to see the light of day … but that also not happened.

0THIS-thinkpad-T25

This slightly modified ThinkPad T470 had dull dark FullHD screen and only one version available. It was also produced in only 5000 pieces … worldwide. It was in 2017 and fast forward 5 years nothing more has happened as we are in 2022 now. Also because only 5000 of them were created its almost impossible to get a used one.

Some people took the matters in their hands and started to make their own modern and modified ThinkPad variations. The most known ones are ThinkPad T62 and ThinkPad X330 with replaced high resolution screens and sometimes even thin bevels along with new hardware underneath of course.

Even today the ThinkPad W520 is quite fast machine. The FreeBSD kernel compilation takes about 600 seconds. On the fresh brand new System76 laptop with also 4 core Intel i7-1165G7 CPU and same 32 GB RAM it takes 300 seconds. Keeping in mind that there are 11 years between these laptops this does not seem that much to be honest.

About quarter ago I changed my employer and got new business laptop – the brand new ThinkPad T14 GEN 1 one.

0THIS-T14-screen

It has the same keyboard layout as ThinkPad W530 which is kinda good remembering how fucked up was the Dell Latitude E7280. The biggest issue with these keyboards (T14/W530) is the lack of empty space between ESC and F1 keys. If you switch desktops with ALT-F1 to ALT-F4 keys then you need to ‘waste’ some more time to make sure you are not doing the ALT-ESC shortcut which is for something entirely else. Its also good to be back on X11 as my new employer allows you to choose RHEL instead of Windows.

Back to ‘personal’ laptops – if my ThinkPad W520 would break I would just get another one … and another … or ThinkPad T520 if W520 would not be available. If for some reason I would not be able to use them anymore I would probably get that:

  • cheapest laptop with enough cores/RAM and FullHD screen
  • wireless “tenkeyless” keyboard in front of that laptop

Maybe I will even put that ‘proper’ keyboard on top of the builtin one to save space.

0THIS-future

It will take little more space but at least it will be usable and productive.

Generation Lost in the Bazaar

For long time I assumed that a lot other people also lack that keyboard layout. Seems I was partially wrong. One of my mates realize me that a lot of people grown up even without ever using the INS/DEL HOME/END PGUP/PGDN layout. I will quote him below.

I didn’t know I was raised without those keys!
I mean, they were there but I wasn’t taught how to use them properly.
And now it seems we can’t find them so frequently…

If like me you went to school in Poland you would probably know (or at least recall a little) a poem of Polish poet JΓ³zef Ignacy Kraszewski titled called Birds in a Cage. Let me quote it for you here as its not that long.

Birds in a Cage
‘Why do you weep?’ a young canary said to an old canary,
‘You are better off now in a cage than you were in the fields.’
‘You were born in it,’ said the old one, ‘so I forgive you;
I was once free but now I’m in a cage and that is why I am weeping.’

Why do I quote it here? Because its very similar to the situation of new laptops available now. Those who do not know the oldschool modular laptops with 7-row keyboards are kinda born in a cage. They pick their MacBook or latest ThinkPad X1 Carbon machines with island keyboard layouts and believe that these are the best possible choices. Its was not always like that.

Future

I do not see the (laptops) future in bright lights. I like what PINE64 PineBook or Framework Laptop bring to the table but on the keyboard side … its still the island type dark ages.

Secure Containerized Browser

By default Chromium on OpenBSD (not so) recently got OpenBSD’s unveil(2) support. That means that of you run Chromium with --enable-unveil flag then it will be prevented from accessing anything other than the ~/Downloads directory. No such thing on FreeBSD exists. Firefox or Chromium have access to all files user can read – even to your system sshd(8) keys or even worse to your private keys laying in the ~/.ssh dir. On FreeBSD thanks to its FreeBSD Jails technology we can create secure containerized browser with only access to the specified directory. On my system its the ~/download dir.

You may want to check other desktop related articles in the FreeBSD Desktop series on the FreeBSD Desktop page.

Configuration

We will start with /etc/jail.conf file configuration. For the record – we will be using /jail for our FreeBSD Jails main dir. I will also use /jail dir for the ‘base’ FreeBSD versions tarballs as a convenient place. As I use 10.0.0.0/24 address space I will use 10.0.0.200 for our containerized browser. Feel free to pick other IP from which you will be able to reach the Internet. The /etc/jail.conf is shown below. One thing to note here. As I am using WiFi wlan0 interface I have put that into the Jail configuration. If you use LAN interface (for example em0) then put that instead into this Jail config. As you see from the example below we will be using Firefox browser in out example.

root@host # cat /etc/jail.conf

# GLOBAL
  exec.start = "/bin/sh /etc/rc";
  exec.stop = "/bin/sh /etc/rc.shutdown";
  exec.clean;
  exec.consolelog = "/var/log/jail_${name}_console.log";
  mount.devfs;
  host.hostname = ${name};
  path = /jail/${name};

# JAILS
  firefox {
    devfs_ruleset = 30;
    ip4.addr = 10.0.0.200;
    interface = wlan0;
    allow.raw_sockets;
    allow.sysvipc;
    mount.fstab = "/jail/firefox/etc/fstab";
  }

As you can see we will also be using devfs(8) rules in the /etc/devfs.rules file – shown below. This configuration is needed to have access to sound(4) in our FreeBSD Jail. If you do not need sound then you can delete devfs_ruleset = 30; from the /etc/jail.conf file and also do not add anything in the /etc/devfs.rules file.

root@host # cat /etc/devfs.rules
[sound=30]
add path 'mixer*' unhide
add path 'dsp*'   unhide

If we are about to share the ~/download dir with our containerized browser then we need to somehow add that information to our FreeBSD Jail. We will use the FreeBSD’s mount_nullfs(8) command to mount our currently existing ~/download dir into our FreeBSD Jail. We will use following /jail/firefox/etc/fstab for that purpose.

root@host # cat /jail/firefox/etc/fstab
#SOURCE         #MNT                                      #TYPE   #OPTS       #DUMP/PASS
/data/download  /jail/firefox/usr/home/vermaden/download  nullfs  rw,noatime  0 0

Of course you do not have to share any directory with your containerized browser.

You may as well would want to make this jails start everytime you boot your system. To do that add below lines to the /etc/rc.conf file as shown below.

jail_enable=YES
jail_parallel_start=YES
jail_list="firefox"

Create the Jail

As I use FreeBSD 13.0-RELEASE I would be using also the FreeBSD 13.0-RELEASE Jail for that purpose. If you are running for example FreeBSD 12.3-RELEASE then make sure that you will use FreeBSD 12.3-RELEASE Jail. The Jail version needs to be lower then the host system version. We will now fetch needed FreeBSD ‘base’ file and unpack it within /jail/firefox dir where our container would live. We will also configure several other basic files such as /etc/resolv.conf or /etc/hosts files.

root@host # mkdir -p /jail/BASE /jail/firefox /jail/firefox/usr/home/vermaden/download

root@host # fetch -o /jail/BASE/13.0-RELEASE-base.txz \
    http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/13.0-RELEASE/base.txz

root@host # tar -xvpf /jail/BASE/13.0-RELEASE-base.txz -C /jail/firefox

root@host # echo nameserver 1.1.1.1 > /jail/firefox/etc/resolv.conf

root@host # echo 10.0.0.200 firefox >> /jail/firefox/etc/hosts

root@host # cat << EOF > /jail/firefox/etc/fstab
#SOURCE         #MNT                                      #TYPE   #OPTS       #DUMP/PASS
/data/download  /jail/firefox/usr/home/vermaden/download  nullfs  rw,noatime  0 0
EOF

We will now start our fresh FreeBSD Jail.

root@host # service jail onestart firefox

We can now also see two new mounts in the mount(8) output.

root@host # mount | tail -2
/data/download on /jail/firefox/usr/home/vermaden/download (nullfs, local, noatime)
devfs on /jail/firefox/dev (devfs)

root@host # mount -p | tail -2 | column -t
/data/download /jail/firefox/usr/home/vermaden/download nullfs rw,noatime 0 0
devfs /jail/firefox/dev devfs rw 0 0

You may want to update the FreeBSD version to the most up to date one with freebsd-update(8) commands.

root@host # freebsd-update -b /jail/firefox fetch
root@host # freebsd-update -b /jail/firefox install

Install Needed Packages

Before installing anything we will first switch to the latest branch for the pkg(8) packages to have most up to date software. We will then process to installing the Firefox package. We will also need x11/xauth package for X11 Forwarding process.

root@host # sed -i '' s.quarterly.latest.g /jail/firefox/etc/pkg/FreeBSD.conf

root@host # grep latest /jail/firefox/etc/pkg/FreeBSD.conf
  url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest",

root@host # jls
   JID  IP Address      Hostname                      Path
     1  10.0.0.200      firefox                       /jail/firefox

root@host # jexec 1

(root@jail) # pkg install -y firefox xauth

Create Matching User and Configure sshd(8) Daemon

We will now enter our FreeBSD Jail again for several other needed tasks for our containerized browser to be working. First is creating inside similar user as you currently use inside. Especially with the same UID/GID to have files with proper permissions in your real ~/download directory instead of files with other UID/GID that you will have to chown(8) with root user. As my vermaden user uses UID/GID 1000 I will also use that inside. I will also set simple password that You will only use once – to copy your public SSH key there.

root@host # jexec 1

(root@jail) # echo your-username-password-goes-here | pw user add -u 1000 -n vermaden -m -s /bin/sh -h 0

Now we need to run /usr/local/bin/dbus-uuidgen --ensure once to make sure DBUS is initialized properly. Firefox and many other apps would not start if we omit that step.

(root@jail) # /usr/local/bin/dbus-uuidgen --ensure

Now the sshd(8) daemon. The only thing we need to do is to add it to the system startup and also add X11UseLocalhost no option to its config file.

(root@jail) # sysrc sshd_enable=YES
sshd_enable: NO -> YES

(root@jail) # echo X11UseLocalhost no >> /etc/ssh/sshd_config

(root@jail) # service sshd start

Performing sanity check on sshd configuration.
Starting sshd.

Copy Public SSH Key and Start

Copying your public SSH key is optional but if you omit this step then you would have to type your FreeBSD Jail user password every time you would want to start your secure Firefox instance.

vermaden@host % ssh-copy-id -i ~/.ssh/id_rsa vermaden@10.0.0.200
Password:

Now you can start your containerized browser. I have added some useful flags for ssh(1) client like compression with -C and fastest supported encryption with -c aes128-ctr option. The -X is for X11 Forwarding option. I also added GDK_SYNCHRONIZE=1 to make Firefox yell less πŸ™‚

vermaden@host % ssh -C -c aes128-ctr -X vermaden@10.0.0.200 env GDK_SYNCHRONIZE=1 firefox --new-instance

Now without password you should see fresh Firefox instance.

firefox-fresh

I will now try to play some random video. I can not show you that from an image but the sound also works πŸ™‚

firefox-youtube

Similar setup can be created for other browser if Firefox is not your browser of choice of course. If you are curious how much space it uses its about this:

root@host # du -smx /jail/BASE/13.0-RELEASE-base.txz /jail/firefox 
181 /jail/BASE/13.0-RELEASE-base.txz
1603 /jail/firefox

root@host # du -smx -A /jail/BASE/13.0-RELEASE-base.txz /jail/firefox
181 /jail/BASE/13.0-RELEASE-base.txz
2601 /jail/firefox

I also added the -A flag in second the du(1) command to show you how much more space would be used without the ZFS LZ4 compression.

UPDATE 1 – Use XPRA Instead of X11 Forwarding

Some people complained that this is quite good setup but they were not happy with using X11 Forwarding for the connection method. I decided to add additional XPRA method to connect to our secure containerized browser. First thing you need to do is to install the x11/xpra package on both the host system and also inside the jail container.

root@host # pkg install -y xpra
(root@jail) # pkg install -y xpra

Now – after logging into your user in the Jail container – vermaden in may case – we will use the xpra commands to create new session with Firefox browser.

Lets see if any xpra sessions currently exists.

(vermaden@jail) % xpra list
Warning: XDG_RUNTIME_DIR is not defined
 and '/run/user/1000' does not exist
 using '/tmp'
No xpra sessions found

Seems not. We can not start our Firefox session.

(vermaden@jail) % xpra start --bind-tcp=:14500 --start='firefox --new-instance'
Warning: XDG_RUNTIME_DIR is not defined
 and '/run/user/1000' does not exist
 using '/tmp'
Entering daemon mode; any further errors will be reported to:
  /tmp/xpra/S19958.log
Actual display used: :0
Actual log file name is now: /tmp/xpra/:0.log

We can see in the xpra list command that new session appeared.

(vermaden@jail) % xpra list
Warning: XDG_RUNTIME_DIR is not defined
 and '/run/user/1000' does not exist
 using '/tmp'
Found the following xpra sessions:
/home/vermaden/.xpra:
        LIVE session at :0

We can also see that xpra is now listening on the 14500 port.

(vermaden@jail) % sockstat -l4
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
vermaden python3.8  20781 3  tcp4   10.0.0.200:14500      *:*

root     syslogd    48568 5  udp4   10.0.0.200:514        *:*

We will now move to out host and start graphical xpra client to connect to our FreeBSD Jail with Firefox process.

update1-xpra-main

After clicking the large Connect button we can now enter our Jail address.

update1-xpra-connect

After again clicking the Connect button on the bottom this time we can now se our Firefox browser from our secure environment.

update1-xpra-firefox

After we done our job at more secure Firefox we can now end our xpra session on the jail system.

(vermaden@jail) % xpra stop
Warning: XDG_RUNTIME_DIR is not defined
 and '/run/user/1000' does not exist
 using '/tmp'
xpra initialization error:

(vermaden@jail) % xpra list
Warning: XDG_RUNTIME_DIR is not defined
 and '/run/user/1000' does not exist

As XPRA provides OpenGL acceleration you may verify that fact from your host system using below command.

vermaden@host % xpra opengl

UNIX Mouse Shootout

While most hardcore UNIX users prefer keyboard shortcuts over anything else – and I often align with that view – I really do appreciate good mouse on my UNIX system. In the end its close to impossible to edit images in GIMP without mouse for example. This ‘shootout’ will definitely be subjective as it will be limited only to mice that I own(ed). I will not bore you with all the technical specifications of these devices – you can check them on your own.

Besides – UNIX has two copy/paste buffers instead of just one like in most systems. There is PRIMARY and SECONDARY buffers in X11 for mouse. One is used when you use Copy/Paste options from menus and/or keyboard shortcuts like [CTRL]+[C] and [CTRL]+[V] ones. The other one is used when you just SELECT the text. After releasing the left mouse button (and finishing the selection) you have that text stored in your SECONDARY buffer. You may now paste that with pressing the third/middle mouse button. But the PRIMARY buffer did not changed during that operation so you can also paste the other text you had in your PRIMARY buffer from the earlier [CTRL]+[C] operation. This makes mouse on UNIX more useful – definitely bigger then in other systems.

While Bluetooth is widely used on most mobile phones/tables and even cars now I do not find it desired as the only protocol for the mouse. I do not have anything against it when it comes as an additional possibility like with the Logitech M720 Triathlon mouse – its even nice that way – but I would not use mouse that the only possible way to connect/operate is by Bluetooth protocol. Maybe on a macOS UNIX but definitely not on FreeBSD UNIX πŸ™‚

AMIGA ‘Tank’ Mouse

The first mouse device that I used was the oldschool AMIGA ‘Tank’ Mouse which I used alongside my first computer – AMIGA A600. When I used it or played Cannon Fodder it felt more then up to the task but using only two buttons mouse (without any scroll and third button) in 2021 feels almost impossible for me.

mouse-amiga-tank

It was possible to run AMIGA UNIX (also known as Amix) on AMIGA hardware. That was an AT&T Unix System V Release 4 developed as alternative to default AmigaOS but you needed Amiga A3000UX hardware for that.

amiga-unix

Unfortunately the AMIGA A600 was not supported 😦

Lenovo and ThinkPad Twins

One of my older/earlier mouse models that I used were quite ‘identical’ mouse models Lenovo Wireless USB Mouse (0A36188) and ThinkPad Wireless USB Mouse (0A36193) – both made by Lenovo for the record. They have the same size and work mostly the same but the older one – ThinkPad model (0A36193) – had more responsive third button (the one under the wheel) – the Lenovo (0A36188) kinda needed real strength to press it – that was its downside.

mouse-thinkpad-lenovo

I still own the ThinkPad one (0A36193) and use it from time to time when I travel – the two AA batteries allow quite long operation of more then a month – which is more then enough for my standards.

Its my first mouse that got additional buttons on the scroll wheel for left and right operations – I used it for volume control on my UNIX system which was (and still is) VERY convenient.

While I really like its/their small size – but after some longer use I really miss some more ergonomic shape under my hand. That means that it ‘will do’ for short periods of usage in travel situations but for long work use something more ergonomic then these.

Logitech Marathon M705 (GEN 1)

I got it after more then a year of using Lenovo and ThinkPad mice. It was real upgrade with quite nice profiled shape to the right hand. It was also quite heavy – but that was good – it felt really good to operate in hand. It was branded as very long to use without changing or charging the batteries and it really did provided in that department – I needed to change/charge the batteries maybe once a year or less often. It was also more precise then simple ThinkPad/Lenovo mouse.

mouse-M705-GEN1

The volume buttons from the wheel that I used on the Lenovo and ThinkPad mice was not quite possible here. While the mouse have these left/right buttons on the wheel they were clumsy and not very precise – so you loss more time trying to press them properly then doing it the other way. With Logitech M705 I ‘moved’ my volume controls to other two buttons that were available under the thumb button. Fortunately there are two of those additional buttons so it was perfect for volume up and volume down actions.

This is also the first mouse that allowed to toggle the wheel to be ‘clickless’ – you can literally spin it for several seconds without any resistance – it just keeps rolling itself – and to be honest – that is one of the features I now DEMAND from any mouse. It makes life so much better (and faster). Instead of scrolling many – many times to get where its needed – you just spin it once and wait till you get there – and even a lot faster then with ‘traditional’ clicking mouse wheel.

Another advantage of that approach is that tip of your finger does not hurt after all day long of scrolling … and if you need precision clicking wheel – then just toggle it and you can click-scroll as usual.

With LogitechΒ Marathon M705 mouse I also grow another ‘useful’ habit (or need) in a mouse. I started to use the lower thumb button to toggle between pause/play for my Deadbeef music player. Before that I used to switch to Workspace 3 where it plays music and press [C] key to toggle pause/play. After adding additional deadbeef --play-pause action to my xbindkeys(1) config now all I have to do to toggle between play and pause is to just push my thumb mouse button. Way faster πŸ™‚

Logitech Performance MX

After reading many comparisons with Logitech MX Master generations I finally settled on the Logitech Performance MX mouse. It is really big and that is really big advantage. It handles/lies really nice in a hand and being quite large and heavy it is very precise and you got ‘good’ feeling and confidence of using it. I really liked it till I got to know its two big downsides … first was the battery time. I needed to change/charge battery about once a week. That was REALLY disappointing. The other downside was that it was not able to properly operate on a flat WOOD surface (like on the photo below). Plain simple flat wood. All other mice worked well on this surface while this one did not. The marketed Darkfield sensor was useless. These were the two reasons that I got rid of it.

mouse-logitech-performance-MX

Same as with M705 the left/right buttons on the wheel were not very precise so I used the additional thumb buttons for volume management. The Logitech Performance MX mouse also comes with micro USB port at the front so you may use the mouse while you are charging it. Its real pity that Logitech did not used two (or even three) AA batteries for this mouse to make it last longer … but that would not resolve the Darkfield sensor not able to cope with movement on the wood πŸ™‚

Logitech Marathon M705 (GEN 2)

I have read a lot of hate and disappointment about the latest generation of Logitech Marathon M705 mouse. Also the lower thumb button is missing and currently it uses only one AA battery. It still provides very long time without the need to change/charge and its lighter now. Its neither bad nor good – its just different. The precision is similar but after using Logitech Performance MX you really miss that big size.

mouse-M705-GEN2

The second generation of M705 did not improved the left/right buttons on the wheel so I decided to stick with additional thumb buttons for volume management.

I also really missed that lower thumb button that is gone from the GEN 2 Logitech Marathon M705 mouse – needed to go back to my [C] routine …

Logitech Triathlon M720

I recently got the possibility to check and use the Logitech Triathlon M720 mouse and I must say that I am positively surprised. Its both Bluetooth and USB dongle mouse so you can choose which way you would like to connect it to your computers. The plural form is intended here as the Logitech M720 allows you to switch between 3 computers with additional dedicated button. It also got ‘back’ the lower thumb button that was missing on the latest generation of the Logitech M705 mouse. The light/white lower bottom of the mouse looks little strange though … but its kinda not visible when it is laying on the table.

mouse-M720

The M720 has more precise left/right buttons on the wheel but I got so used to manage volume with my thumb that I currently keep these ‘wheel’ buttons unused.

Having the lower thumb button again I was also able to get back to my toggle play/pause Deadbeef operation. Yay!

Another useful use case I discovered recently is the ‘misuse’ of the button that switches between 3 computers. I started to use it to ‘suspend’ (generally off) the mouse if I do not want the mouse to ‘wake’ the screen – to not accidentally turn on the screen when I move the mouse accidentally. I mean – sometimes I turn off the screen (with shortcut that executes xset dpms force off command) and then I switch the mouse M720 mouse to channel number 2 to it will not be able to communicate with USB receiver and turn on my screen in again accidentally.

Missing

I never owned Logitech MX Master mouse. I used version ‘3’ for short time as one of my buddies own it and it felt quite similar to Logitech Performance MX in operation but not quite the same. Similar but different. I think that it would be comfortable but not sure about the precision on wood and battery time. Maybe I will got it some day and add an update here.

mouse-MX-master

… but given the fact that Logitech MX Master mouse also has micro USB port at its front for charging I would suspect that battery time is also not that great. Similarly like the Logitech Triathlon M720 it also allows to switch its presence between 3 computers. There is also additional wheel for vertical scrolling. Never used that but maybe it would be useful in GIMP for example.

Summary

So what does a good UNIX mouse feature? I would summarize all the needed (or at least useful) feats in a list below.

  • needs to be at lest a little ergonomic
  • allows to toggle wheel between click and clickless operation
  • have additional buttons for custom actions
  • allows more then one month of work on batteries
  • works on different surfaces without a problem
  • has a USB dongle so Bluetooth is not needed

What other features you desire in mouse? I also thought about ‘vertical’ mouse type/shape and also about trackball. I tried my neighbor Logitech trackball several times but I am not sure I would get used to it after so many years of ricing the mice πŸ™‚

FreeBSD Desktop – Part 26 – Configuration – Conferencing and Meetings

For years I thought that online video conferencing and/or meetings would not be possible on FreeBSD. One of the first things I done on each of my laptops was to disable Camera and Microphone (along with Bluetooth) to save some battery time. While the Microphone would probably work I did not even tried to use it – did not had such needs to record anything with my laptop.

As time passed by I thought that maybe I will try what is the state of using Camera on FreeBSD and also how it is doing in the video conferencing/meetings space.

thinkpad-meet-800

I was really astonished by the results … at least on my ThinkPad W520.

The Table of Contents for the article:

  • Camera Setup
  • Microphone Setup
    • ThinkPad Microphone Easter Egg
  • Meetings
  • Closing Thoughts

You may want to check other articles in the FreeBSD Desktop series on the FreeBSD Desktop – Global Page where you will find links to all episodes of the series along with table of contents for each episode’s contents.

Camera Setup

I enabled Camera and Microphone in the BIOS (leaving Bluetooth disabled) and booted up my FreeBSD 13.0 as usual.

I then installed needed packages which are:

  • multimedia/v4l-utils – Video4Linux utilities
  • multimedia/v4l_compat – Video4Linux IOCTL header files
  • multimedia/pwcview – Video4Linux PWC webcam viewer
  • multimedia/webcamd – port of Linux USB webcam and DVB drivers

We will also need to load cuse.ko kernel module at each boot. We will use /etc/rc.conf for that.

# pkg install v4l-utils v4l_compat webcamd pwcview

# vi /etc/rc.conf

  kld_list="${kld_list} cuse"

:wq

My Camera is listed at the end of the usbconfig(8) command.

We will use above webcamd(8) output to add needed webcamd_0_flags in the /etc/rc.conf file.

# vi /etc/rc.conf

  webcamd_enable=YES
  webcamd_0_flags="-d ugen0.5"

:wq

We also need to add ourselves to the webcamd group.

# pw groupmod webcamd -m vermaden

# grep webcamd /etc/group 
webcamd:*:145:vermaden

We can now start the webcamd(8) daemon.

# service webcamd start
Starting webcamd.

We will now use pwcview(1) to check how the Camera works.

% pwcview
Webcam set to: 320x240 (sif) at 5 fps

Here is how it looks.

Works! I pixelised the output as I do not have an instagrammer soul …

You can start pwcview(1) with larger resolution when needed.

Camera at mine ThinkPad W520 tops at 1280×720 resolution (HD) and 30 fps for refresh rate.

ThinkPad Microphone Easter Egg

After I successfully tested the Camera on my ThinkPad W520 I then moved to Microphone testing … to just find out that my microphone is totally deaf. I could not record any sound with audacity(1) or ffmpeg(1).

At the beginning I first suspected it was a FreeBSD problem … unjustifiably fortunately.

Switching Microphone to [Enabled] in the ThinkPad W520 BIOS requires special procedure as shown on the BIOS screenshot below πŸ™‚

thinkpad-bios

1. Set the Microphone to [Enabled].
2. Select Save and Exit option in BIOS.
3. Power off laptop.
4. Disconnect AC power for at least 10 seconds (battery can be attached).
5. Power on laptop.
6. Boot FreeBSD as usual and now recording on Microphone works like a charm πŸ™‚

Why so strange enabling procedure? Some people suggested that it needs to be that complicated to make sure that any third party will not enable your Microphone without your knowledge. Security concerns. Makes sense.

Meetings

I was able to successfully start/join Google Meet and Zoom and also Teams meetings with this setup. I have also tested and added Jitsi Meet.

Sometimes it just required to use www/chromium instead of my default www/firefox browser.

Here is the detailed list of what works where.

Closing Thoughts

Hope that will helps some of you to use join your meetings on FreeBSD system.

FreeBSD Desktop – Part 25 – Configuration – Random Terminal Theme

Some time ago when I was mostly writing about Openbox setup I also showed how to setup xterm(1) so it will start with new random theme with each start. Since then I reworked that feature a little and also added random theme and background selection for urxvt(1) terminal. This post will guide you through the needed steps to make that setup working.

terminal

You may want to check other articles in the FreeBSD Desktop series on the FreeBSD Desktop – Global Page where you will find links to all episodes of the series along with table of contents for each episode’s contents.

I already once wrote about random xterm(1) themes in the FreeBSD Desktop – Part 12 – Configuration – Openbox part – but I really wanted to expand that topic and also include other terminals.

After trying many terminal emulators – some more bulky like Konsole/GNOME Terminal/XFCE Terminal/MATE Terminal – some more lightweight like st(1)/rox-term(1)/eterm(1)/… – I always went back to the most old-school and basic one – good old xterm(1) terminal. Mostly because of its good compatibility with all UNIX systems – especially the older ones like IBM AIX or HP-UX. I do not remember last time when I had to manage these archaic systems but the respect for xterm(1) remains.

xterm

The other one that always got my attention was urxvt(1) terminal. Unfortunately it has some issues with fonts rendering – making larger spaces between the lines and making fonts bigger for example – but as I also like bitmap fonts like CLEAN or FIXED – so I use bitmap fonts for urxvt(1).

Recently also sakura(1) got my attention – but it’s theming possibilities are even more limited then xterm(1) with themes/colors hardcoded directly into the source code. That is why I will omit it in this article – but I mention it since its also nice terminal.

This is the Table of Contents for this article.

xterm(1)

First lest start with some reasonable configuration in the ~/.Xdefaults file. Alternatively some people use ~/.Xresources file. You can use any of them. Just pick one and stick to it.

                            <btn1up>: select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0) \n\
                            Ctrl <key> minus: smaller-vt-font()                   \n\
                            Ctrl <key> plus: larger-vt-font()                     \n\
                            Ctrl Shift <key> C: copy-selection(CLIPBOARD)         \n\
                            Ctrl Shift <key> V: insert-selection(CLIPBOARD)

I will not discuss all possible settings as they are well described in the xterm(1) man page but I will comment some more useful and interesting ones.

Proper Font Selection

This advice is not limited to xterm(1) but its worth to mention it. Many times after adding fonts to my system – and renaming them to my ‘standard’ which looks like that one below I was asking myself how to properly specify the variant I need.

% ls -1 ~/.fonts/ubuntu-mono*
/home/vermaden/.fonts/ubuntu-mono-bold-italic.ttf
/home/vermaden/.fonts/ubuntu-mono-bold.ttf
/home/vermaden/.fonts/ubuntu-mono-italic.ttf
/home/vermaden/.fonts/ubuntu-mono.ttf

The answer to that question comes with fc-match(1) from fontconfig package. Check my ‘queries’ below.

% fc-match consolas:bold
consolas-bold.ttf: "Consolas" "Bold"

% fc-match consolas     
consolas.ttf: "Consolas" "Regular"

% fc-match consolas:bold:italic
consolas-bold-italic.ttf: "Consolas" "Bold Italic"

Selecting Text for Copy/Paste

The xterm*charClass defines which sets of characters should be treated the same when doing cut and paste. Especially with double-clicking the text. The setting above I use is based on 15 years of experience and seems to work best. You are of course encouraged to investigate the CHARACTER CLASSES section of the xterm(1) man page to read more on this topic.

The xterm*on4Clicks and xterm*on5Clicks are not used by default while xterm*on2Clicks are predefined as word and xterm*on3Clicks as line values. This is why I added them so you can select entire group with xterm*on4Clicks and entire page with xterm*on5Clicks option. Alternatively you can also use some fancy regex for some of these ‘CLICKS’ but I never thought about a REGEX that would be useful here – maybe you will come with something sensible.

Here are these ‘CLICKS’ in action.

First the xterm*on2Clicks with word selection. This is when the xterm*charClass is taken into account – what is word and that is not πŸ™‚

xterm.2.clicks

Then xterm*on3Clicks with line selection.

xterm.3.clicks

Now xterm*on4Clicks with group selection.

xterm.4.clicks

Finally the xterm*on5Clicks entire page selection.

xterm.5.clicks

Selection Buffers and Keyboard Shortcuts

The last interesting option is xterm.VT100.translations which is used for keyboard shortcuts.

The first one select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0) is better described in the https://davidsimmons.com/soft/xtermhacks/ page from 2005. I will try to short the meritum here. The X11 applications have two different selection buffers:

CLIPBOARD – selection buffer used for cut/paste functions – you select/highlight text and then select Copy from context menu or use [CTRL]+[C] shortcut. Then you use Paste or [CTRL]+[C] shortcut.

PRIMARY – this one receives data when user selects/highlights text with mouse. None other operations such as Copy or Paste are needed. You end selecting the text and its already in PRIMARY buffer. You then paste it with MIDDLE mouse button.

Using the option above selecting/highlighting the text in xterm(1) copies the text into both selection buffers simultaneously. You can now either Paste it info Firefox or hit MIDDLE mouse button to paste it in other xterm(1) terminal. Best of both worlds.

If that setting does not suit you then use the xterm*selectToClipboard instead. When set to true it copies selected text to CLIPBOARD buffer and when set to false it copies selection to the PRIMARY one.

Increase/Decrease Font Size on the Fly

I always missed the shortcuts to decrease or increase font size on the fly in xterm(1) and for many years I believed that its just not possible and then I found some blog post (do not remember which one now of course) in which I found these settings and started to use them.

They are smaller-vt-font() and larger-vt-font() for decrease and increase respectively with [CTRL]+[-] and [CTRL]+[+] shortcuts – keep in mind that [SHIFT] is not used here.

Copy/Paste with [CTRL]+[SHIFT]+[C/V]

If by some reason you prefer to copy and paste by using [CTRL]+[SHIFT]+[C] and [CTRL]+[SHIFT]+[V] shortcuts then copy-selection(CLIPBOARD) and insert-selection(CLIPBOARD) will do the needed job here. As you probably guessed you can use PRIMARY instead of CLIPBOARD here if that is what you desire.

Interactive Menus

The xterm(1) comes with three different interactive menus. I will now show all three of them here with screenshots.

Menu displayed with clicking [CTRL]+[LEFT-MOUSE-BUTTON] in the terminal area.

xterm.menu.mouse.LEFT

Menu displayed with clicking [CTRL]+[MIDDLE-MOUSE-BUTTON] in the terminal area.

xterm.menu.mouse.MIDDLE

Menu displayed with clicking [CTRL]+[RIGHT-MOUSE-BUTTON] in the terminal area.

xterm.menu.mouse.RIGHT

Random xterm(1) Theme

To have random xterm(1) theme on every startup you need four things:

I gathered all these themes all over the Internet, only the VERMADEN and VERMADEN-OLD themes are created by me.

Little preview of some of the included xterm(1) themes.

xterm.random

From now on to have random xterm(1) theme at each start always start it with ~/scripts/xterm.sh script. The script itself is not very complicated. It just draws random theme from the ~/.config/Xdefaults/themes dir – then loads the ~/.Xdefaults config – then merges the colors from chosen random theme – and finally starts new xterm(1) instance.

xterm.sh

urxvt(1)

I use urxvt(1) less often but still sometimes I want to use bitmap fonts instead.

urxvt.single

For a start here is the urxvt(1) configuration in the ~/.Xdefaults file.

! URXVT
! -----------------------------------------------------------------------------
  urxvt.letterSpace:    0.0
! urxvt.font:           xft:monaco:pixelsize=9,style=regular,minspace=True
  urxvt.font:           -*-clean-*-*-*-*-*-*-*-*-*-*-iso8859-2
  urxvt.boldFont:       -*-clean-*-*-*-*-*-*-*-*-*-*-iso8859-2
  urxvt.iconFile:       /home/vermaden/.icons/vermaden/xterm.xpm
  urxvt.geometry:       150x40
  urxvt.cutchars:       ,;
  urxvt.scrollBar:      false
  urxvt.imLocale:       en_US.UTF-8
  urxvt.loginShell:     true
  urxvt.saveLines:      1024000
  urxvt.inheritPixmap:  false
  urxvt.shading:        20
  urxvt.xftAntialias:   true
  urxvt.jumpScroll:     true
  urxvt.tintColor:      black
  urxvt.internalBorder: 2
  urxvt.cursorBlink:    false
  urxvt.cursorColor:    #dd9900
  urxvt.cursorColor2:   #000000
  urxvt.colorBD:        #dddddd
  urxvt.colorIT:        #bbbbbb
  urxvt.colorUL:        #999999
  urxvt.underlineColor: #999999

Tabbed Interface

To get tabs in urxvt(1) add the following option to the ~/.Xdefaults configuration file.

  urxvt.perl-ext-common:   default,tabbed

With this option you will open new tab with [SHIFT]+[DOWN] shortcut.

To switch between the tabs left and right use [CTRL]+[SHIFT]+[LEFT] and [CTRL]+[SHIFT]+[RIGHT] shortcut respectively.

You can also use [CTRL]+[LEFT] and [CTRL]+[RIGHT] to move current tab left and right.

The timeless [CTRL]+[D] – which of course is not a strictly urxvt(1) shortcut but a general shortcut for closing all terminals.

urxvt.tabbed

Daemon and Client Mode

The urxvt(1) can be run in special daemon mode where you start one urxvtd(1) server and many urxvtc(1) clients.

% urxvtd
rxvt-unicode daemon listening on /home/vermaden/.urxvt/urxvtd-w520.local.

Now you will start each new urxvt(1) terminal with urxvtc(1) command.

The drawback of that approach is that when urxvtd(1) dies or crashes then also all your urxvtc(1) client terminals disappear πŸ™‚

Random urxvt(1) Theme and Background

To have random urxvt(1) theme and background on every startup you need four things:

Little preview of some of the included urxvt(1) themes and backgrounds.

urxvt.random

From now on to have random urxvt(1) theme at each start always start it with ~/scripts/urxvt.sh script. The script for urxvt(1) is little more advanced. First it draws random theme from the ~/.config/Xdefaults/themes dir – then checks if its DARK or LIGHT theme – then draws either random LIGHT or DARK background from the ~/.config/Xdefaults/urxvt dir – finally loads the ~/.Xdefaults config and then merges the colors from chosen LIGHT or DARK theme. Of course then it finally starts new urxvt(1) instance.

urxvt.sh

sakura(1)

The more modern and GTK based sakura(1) also supports tabs. To open new tab use [CTRL]+[SHIFT]+[T] shortcut. To switch between the tabs use [CTRL]+[ALT]+[LEFT] and [CTRL]+[ALT]+[RIGHT] shortcuts. You can also move tab between left and right with [CTRL]+[SHIFT]+[LEFT] and [CTRL]+[SHIFT]+[RIGHT].

sakura.single

One things that sakura(1) impresses me is that you can scale down its window and then scale that window up and the contents that did not fit in the window after downscalling are back again in the terminal. Doing the same operation in xterm(1) or urxvt(1) terminals will result in these characters being lost. The output is also dynamically ‘fit’ into the new larger window while maintaining the new lines etc. Besides that nice feature it is small and fast and uses relatively small amount of RAM.

sakura.tabbed

Different sakura(1) Themes

If you would also like to start sakura(1) with different theme everytime the options are quite limited here. The palettes and color sets are hardcoded into the sakura(1) source code.

I will not show you how to modify them using the FreeBSD Ports system.

The sakura(1) port is located at /usr/ports/x11/sakura directory. For the record – I use WRKDIRPREFIX option in the /etc/make.conf file. This means that when I type make extract in the /usr/ports/x11/sakura dir the work directory will not be created at /usr/ports/x11/sakura/work directory but at /usr/ports/obj/usr/ports/x11/sakura/work instead. That way I can clean my Ports tree fast by removing the /usr/ports/obj directory.

We will now extract and patch the sakura(1) port on FreeBSD.

% grep WRKDIRPREFIX /etc/make.conf
WRKDIRPREFIX=${PORTSDIR}/obj

# cd /usr/ports/x11/sakura

# make patch

# cd /usr/ports/obj/$( pwd )/work/*/src || cd work/*/src

# pwd
/usr/ports/obj/usr/ports/x11/sakura/work/sakura-3.7.1/src

# grep -m 1 DEFAULT_PALETTE sakura.c
#define DEFAULT_PALETTE "tango"

# grep -o -E '[a-z]+_palette\[PALETTE_SIZE\]' sakura.c
gruvbox_palette[PALETTE_SIZE]
tango_palette[PALETTE_SIZE]
linux_palette[PALETTE_SIZE]
dark_palette[PALETTE_SIZE]
xterm_palette[PALETTE_SIZE]
rxvt_palette[PALETTE_SIZE]

As you can see the default sakura(1) palette is Tango. Fortunately you can use palette=solarized_dark option in the ~/.config/sakura/sakura.conf config file to change it into Solarized Dark for example.

Besides hardcoded palettes sakura(1) also has several Color Sets.

If you would like to make random theme (from the hardcoded ones) for each start you would have to use this syntax with prepared dedicated config files for each palette.

% sakura --config-file ~/.config/sakura/sakura.solarized_dark.conf --colorset 1 
% sakura --config-file ~/.config/sakura/sakura.tango.conf          --colorset 3

I do not use sakura(1) that much so I was too lazy to write random startup theme script also for it πŸ™‚

Changing sakura(1) palette or color set manually is shown below.

sakura.colors.menu

sakura.colors.window

sakura.palette

RAM Usage Comparison

Just started xterm(1) terminal takes about 16 MB or RAM as you have seen on the urxvt(1) screenshots. The urxvt(1) started without tabs uses more then 2 TIMES of xterm(1) terminal RAM usage. The urxvt(1) started in tabbed mode uses more then 3 TIMES of xterm(1) terminal RAM usage. The sakura(1) also uses more then 3 TIMES of xterm(1) terminal RAM usage.

Table below shows RAM usage comparison. I have added more feature packed mate-terminal(1) to the list and also added the st(1) minimalistic terminal from Suckless project for compassion.

RAM/MB  TERMINAL  
    64  mate-terminal
    53  sakura
    52  urxvt (tabbed)
    38  urxvt
    16  xterm
    12  st

CPU Time Usage Comparison

I also made simple benchmark of the CPU used. The ‘benchmark’ was to check how much time each terminal would take to print output ofΒ  dmesg | lolcat -b -r command. Here xterm(1) does not shine that much.

   TIME  TERMINAL
0:00.93  xterm
0:00.82  mate-terminal
0:00.52  sakura
0:00.43  urxvt
0:00.23  st

The above ‘benchmark’ was was quite ‘hard’ because of all the colors generated by lolcat(1) command. Lets try something more practical now. We will measure CPU time used to display out of the find find /usr/local/share/doc command.

   TIME  TERMINAL
0:01.34  xterm
0:01.18  mate-terminal
0:00.85  sakura
0:00.32  urxvt
0:00.28  st

Seems that lolcat(1) was not that ‘hard’. The st(1) minimalistic terminal really seems to suck less here πŸ™‚

FreeBSD Desktop – Part 24 – Configuration – Universal File Opener

More then a decade ago when I started to use X11 as a desktop – on Linux then with KDE3 and later with Fluxbox. At first I thought that files are opened by appropriate applications not by their extension as in Windows systems but according to their Magic Numbers. I do not have to tell you how much disappointed I was when I learned the truth πŸ™‚

You may want to check other articles in the FreeBSD Desktop series on the FreeBSD Desktop – Global Page where you will find links to all episodes of the series along with table of contents for each episode’s contents.

TL;DR

Its a short story about cleaning the mess that XDG does and also using custom *.desktop handlers to open the files in the way you want. It know its in the FreeBSD Desktop series but actually it will work on any X11 desktop like Linux or Illumos.

The Table of Contents for the article is right below here.

  • XDG Utils
  • Now You See Me
  • Mime Apps Handlers
  • Generation of Handlers
  • Alternatives

Lets start then.

XDG Utils

After years of using X11 on FreeBSD now with Openbox as my daily driver I used so called xdg-utils package with its *.desktop files. That sometimes driven me nuts. Mess everywhere with doubled ‘the same’ applications listed as possible choices to open a file … almost randomly generated new *.desktop handlers with ‘new’ applications specified to open some files … another dozen of generated *.desktop files from WINE installations … it can only challenge the bullshit and mess of Windows Registry … not sure which one is more messed up (of course its Windows Registry but still).

The xdg-mime(1) is often not useful at all then determining the file type.

$ xdg-mime query filetype FILE.pdf
application/pdf

$ xdg-mime query default application/pdf
mupdf.sh.desktop

If minimalistic mupdf approach is not for you then you can select Atril for example … but you first need to know that is the handler name for the Atril application. You can find that out fast like that.

% find ~/.local/share/applications /usr/local/share/applications | grep atril
/usr/local/share/applications/atril.desktop

We now have the Atril handler name. To set it as new default application for PDF files type the following.

$ xdg-mime default atril.desktop application/pdf

$ xdg-mime query default application/pdf
atril.desktop

But this is rather unique moment when XDG works as designed. More often it looks like that.

$ xdg-mime query filetype FILE.doc
application/octet-stream

$ xdg-mime query filetype FILE.docx
application/zip

$ xdg-mime query filetype FILE.xls
application/octet-stream

$ xdg-mime query filetype FILE.xlsx
application/zip

So when you now ask for application/zip type then what should pop up? LibreOffice for Word/Excel documents or Engrampa for ZIP files?

% xdg-mime query default application/zip                                     
engrampa.desktop

Now You See Me

After almost accepting the current ‘tragic’ state of it I came with other idea – to create mine simplified launcher for many of these file types. It started small and is still quite small. The only thing I do now is that I only add new apps for file extensions that are not yet defined.

Its called see.sh and its function is dual:
– to easily replace XDG settings in one place as file opener
– as command line opener for single or multiple files

The construction of see.sh is really simple. It utilizes the idea behind the quote of Antoine de Saint-Exupery which goes like that – “Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.” – its really simple and has nothing to remove from it.

I really appreciate that idea that I now do not have to remember which application is needed (and how its spelled besides the zsh(1) TAB completion) to open any file in command line. Its also faster to type then xdg-open(1) and I am sure that its settings were not modified by some third party app that I just installed because its hardcoded in it.

I also really like see.sh for being very elastic for the environment variables with which the needed application can be started. For example my default DPI for X11 session since more then a decade is 75. That makes fonts little smaller – more information fits on the available screen space. The GTK2/GTK3 applications do not need any tweaks and always look decent or even great but QT5 (and QT4 not so long ago) apps are real bitches when you want to force them to look the way you want (look nice) – especially when run without fully fledged KDE or PLASMA environment. One of such applications is LibreOffice. It looked great when it used GTK framework but after they moved to QT it started to look very ugly with my 75 DPI setting. This is how it looks with its environment unmodified.

Thanks to see.sh I can start LibreOffice with different DPI environment setting then 75 and it looks little better with DPI set to 80. LibreOffice started with QT_FONT_DPI=80 option does not look that bad now – its fonts are not that small and ugly anymore.

Now the text labels on LibreOffice menus are more readable but also not too large.

You may also customize see.sh to first create a backup copy before editing certain files or email them – only your imagination limits you here.

I also wanted its see.sh name to be short and fast to type so with completions its just see[TAB] and then a filename. Of course you may want to rename it to shorter version (or create alias) as see without extension but i like to keep my scripts with extension to distinguish them from native commands – but that is me.

First see.sh detects if one or multiple arguments (files) have been passed to it. If its just a single file then see.sh detects its extension and launches the configured application for it.

If file does not have extension then it checks file’s Magic Number. Currently only detection for plain text files is implemented with file(1) command.

If you pass multiple arguments (files) to see.sh then separate see.sh processes will be launched against each given file in parallel. Recursion generally.

Every time you select new application in graphical mode the new *.desktop file is created as a result with userapp-${APPNAME}-${RANDOM_STRING}.desktop name under ~/.local/share/applications directory. I am not sure that its the tidiest way possible. Often very ugly and strange handler filenames are generated – with spaces or quotation marks. Its really far from UNIX way of doing things and its philosophy.

This is how ~/.local/share/applications directory looked on my machine after some time. Notice the selected file.

After some cleanup and modifications it looks little better.

The XDG keeps its associations in the ~/.config/mimeapps.list file. Have a look how messed it gets after some usage.

After some more cleanup and removal of all unneeded userapp-${APPNAME}-${RANDOM_STRING}.desktop entries it starts to look more organized.

Every time see.sh will find out that it does not have handler for a file it will gracefully remind one to configure it.

Mime Apps Handlers

Many of these *.desktop handlers are not present anymore … but which one? Here is a handy one liner that will either show you the full path of the handler or ‘NOPE’ when one does not exists. This will also tell you if its your ‘custom’ handlers at ~/.local/share/applications or the ‘default’ ones that come with packages and installed software located at /usr/local/share/applications location.

% awk -F'=' '{print $2}' ~/.config/mimeapps.list \
    | tr ';' '\n' \
    | sort -u \
    | sed 1d \
    | while read I
      do
        echo ${I}
        find \
          ~/.local/share/applications \
          /usr/local/share/applications \
            | grep "/${I}" || echo NOPE
        echo
      done

Well … maybe not exactly ONE liner but a useful command that will do it πŸ™‚

Here is its output.

(...)

mupdf.sh.desktop
/home/vermaden/.local/share/applications/mupdf.sh.desktop

planmaker-free18.desktop
NOPE

presentations-free18.desktop
NOPE

see.sh.desktop
/home/vermaden/.local/share/applications/see.sh.desktop

sumatra.sh.desktop
/home/vermaden/.local/share/applications/sumatra.sh.desktop

textmaker-free18.desktop
NOPE

(...)

If you just want to check which ones are missed then add grep -B 1 NOPE at the end.

% awk -F'=' '{print $2}' ~/.config/mimeapps.list \
    | tr ';' '\n' \
    | sort -u \
    | sed 1d \
    | while read I
      do
        echo ${I}
        find \
          ~/.local/share/applications \
          /usr/local/share/applications \
            | grep "/${I}" || echo NOPE
        echo 
      done | grep -B 1 NOPE

Here is the (un)expected output.

You can safely remove all missing *.desktop handlers from the ~/.config/mimeapps.list file. You may use sed(1) or graphical editor if that suits you better. The logic behind it is to remove all instances of for example presentations-free18.desktop and then find and replace all instances of doubled semicolons ‘;;‘ into single one ‘;‘.

Generation of Handlers

To generate new *.desktop handlers in orderly fashion you can use mine generate-desktop-handler.sh script. It will create new handler in the ~/.local/share/applications directory and it will make sure you are creating one with an application that actually exists. Here is how it works. I have created new handler for my random-wallpaper-always.sh for setting up random wallpaper from specified directory or to set wallpaper from exact specified file as argument.

% generate-desktop-handler.sh                                       
usage: generate-desktop-handler.sh FILE

% generate-desktop-handler.sh non-existing-executable
NOPE: executable 'non-existing-executable' not found in ${PATH}

% generate-desktop-handler.sh random-wallpaper-always.sh 
INFO: handler '~/.local/share/applications/random-wallpaper-always.sh.desktop' was successfully generated

% cat ~/.local/share/applications/random-wallpaper-always.sh.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
NoDisplay=true
Exec=random-wallpaper-always.sh %f
Name=random-wallpaper-always.sh
Comment=random-wallpaper-always.sh

After you have created new random-wallpaper-always.sh.desktop handler you may want to add it to some image file type like JPG or PNG. In the example below I will add it to JPG file.

First right click on a JPG file with mouse and select Open With and then Other Application….

The select random-wallpaper-always.sh.desktop handler on the list. Make sure to UNCHECK the Remember this application for … files option. If you do not do that it will be the DEFAULT application from now and everytime you would want to open JPG file you will set it as wallpaper πŸ™‚

You may verify that new option is added by right clicking the JPG file and selecting Properties and then go to Open With tab. The random-wallpaper-always.sh.desktop handler will be one of the configured handlers for JPG files – but not the default one.

Now you can see that random-wallpaper-always.sh.desktop handler is available to use when selecting the Open With submenu.

As simple as that – and with tidiness as well.

Alternatives

There are some other alternatives to XDG but I am more then sure that most or all X11 applications support XDG way of doing things while not support the other alternative ones. Thus its far less hustle with just making XDG work as desired by generating needed handlers and using see.sh instead of using them and wasting even more time on the topic – at least that is my current experience.

Feel free to share your thoughts on the topic – maybe you will show me even better approach to this.

FreeBSD Desktop – Part 23 – Configuration – Herbe Notifications

I do not use notifications. Dunno really why – seems I just did not needed them. The idea of Do Not Disturb Mode on the desktop/laptop is very strange to me as I ALWAYS work in the Do Not Disturb Mode since I do not use any notifications. Today I came across very small and compact solution for notifications on X11 desktop – herbe – as its author describes it – its daemon-less notifications without D-Bus. Minimal and lightweight.

I was curious if it works on FreeBSD and apparently it is πŸ™‚

Today I will show you how to build, configure and use herbe as part of FreeBSD Desktop series.

You may want to check other articles in the FreeBSD Desktop series on the FreeBSD Desktop – Global Page where you will find links to all episodes of the series along with table of contents for each episode’s contents.

Fetch

We will use the compact git-lite package from FreeBSD which has less dependencies then the default git package. Then we will clone the herbe repository.

# pkg install git-lite

Patch

We will need a tiny one line patch to make it build on FreeBSD.

This FreeBSD patch for Makefile file is available here:
https://github.com/dudik/herbe/pull/16

… or diff(1) directly here:
https://patch-diff.githubusercontent.com/raw/dudik/herbe/pull/16.diff

We will now apply that patch.

% fetch https://patch-diff.githubusercontent.com/raw/dudik/herbe/pull/16.diff

The herbe is now buildable on FreeBSD.

There are also other available patches – herbe patches – available here.

From all of them I find Vertical Stacking patch the most interesting. We will also apply it.

Config

You can additionally patch herbe so it will be configurable by using ~/.Xresources or ~/.Xdefaults files. IMHO its so small and compiles in second that its not needed but if you would like to also apply it then its available here – Xresources – in the patches section.

I have chosen to configure it using the config.def.h file. Here are my values.

% cat config.def.h
static const char *background_color    = "#222222";
static const char *border_color        = "#666666";
static const char *font_color          = "#eeeeee";
static const char *font_pattern        = "Ubuntu Mono:size=10";
static const unsigned line_spacing     = 5;
static const unsigned int padding      = 15;

static const unsigned int width       = 550;
static const unsigned int border_size = 4;
static const unsigned int pos_x       = 15;
static const unsigned int pos_y       = 45;

enum corners { TOP_LEFT, TOP_RIGHT, BOTTOM_LEFT, BOTTOM_RIGHT };
enum corners corner = TOP_RIGHT;

static const unsigned int duration = 5; /* in seconds */

#define DISMISS_BUTTON Button1
#define ACTION_BUTTON Button3

Build

The build process could not be simpler. Just type make and you are done.

% make 
cp config.def.h config.h
cc herbe.c -Wall -Wextra -pedantic -I/usr/local/include -L/usr/local/lib -lX11 -lXft -I/usr/local/include/freetype2 -pthread -o herbe

% file -s herbe | tr ',' '\n'

 interpreter /libexec/ld-elf.so.1

% ./herbe 
Usage: ./herbe body

Test

I did not yet implemented herbe anywhere on my scripts so I will use this simple ‘mockup’ to show you what to expect.

% \
  herbe "Wifi connection 'wireless' is not connected." \
& herbe "Removable storage /dev/da0 automounted at /media/da0 with exFAT filesystem." \
&

Here is how it looks in real life X11 session.

As you can see it works very well and its ultra fast. Its also very light on system resources.

% ps aux | grep -e RSS -e herbe -e sshd
USER       PID  %CPU %MEM      VSZ     RSS TT  STAT STARTED        TIME COMMAND
vermaden 41909   0.0  0.1    19568    9128  3  S+   20:22       0:00.02 herbe Message.

As you can see its RAM usage is very little – as little as sshd daemon.
