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.

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.

I also do not rely on ‘stock’ fan speeds and set my own speeds according to CPU temperature with acpi-thinkpad-fan.sh script.

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.

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.

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).

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.

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™‚
