Here are some notes on installing Debian Squeeze on a Thinkpad X121e. Before following this guide, check the system details (at the end of this post) to see if you have the same model of graphics card, wifi, ethernet, etc.

Installation notes Link to heading

The ethernet card is not detected by the Debian installer, so at the first opportunity flip to a console, load the atl1c driver, and echo this magic string:

modprobe atl1c
echo "1969 1083" > /sys/bus/pci/drivers/atl1c/new_id

Wrong resolution in xorg Link to heading

The installation process runs ok but on rebooting the screen resolution in xorg was 1024x768 instead of 1366x768 so everything looked weird and squashed. Upgrading to a 3.2 kernel fixes the problem. Add this line to /etc/apt/sources.list:

deb http://backports.debian.org/debian-backports squeeze-backports main

then install the new kernel:

sudo apt-get update
sudo apt-get install -t squeeze-backports  linux-image-3.2.0-0.bpo.2-amd64  # (previously said: linux-image-2.6.39-bpo.2-amd64 which is wrong)

After rebooting into the new kernel the resolution should be ok. If graphics are slow (e.g. moving an xterm flickers) then also grab the backported xorg packages:

sudo apt-get install -t squeeze-backports xorg xserver-xorg xserver-xorg-core 
xserver-xorg-input-all xserver-xorg-video-all

Broadcom wifi driver Link to heading

Getting the Broadcom wifi driver to work with the 3.2 kernel was not completely straightforward. The Debian Wiki says to install the broadcom-sta-source model and then compile it with module-assist:

sudo apt-get install broadcom-sta-source
sudo apt-get install module-assistant
sudo m-a prepare

Getting source for kernel version: 3.2.0-0.bpo.2-amd64
apt-get install kernel-headers-3.2.0-0.bpo.2-amd64
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package kernel-headers-3.2.0-0.bpo.2-amd64
E: Couldn't find any package by regex 'kernel-headers-3.2.0-0.bpo.2-amd64'

This fails because the backported kernel header package is not called kernel-headers-3.2.0-0.bpo.2-amd64; it is actually linux-headers-3.2.0-0.bpo.2-amd64. Fortunately we can install the headers ourselves:

sudo apt-get install -t squeeze linux-headers-3.2.0-0.bpo.2-amd64

Now try the module-assist again:

sudo m-a update
sudo m-a a-i broadcom-sta

However we are compiling against the 3.2 kernel, and the broadcom-sta package in Squeeze is not new enough. It failed with an error about C pointers (sorry, forgot to save the details). However, happysumo on Whirlpool had a similar issue and suggested temporarily updating to the testing distribution. So edit /etc/apt/sources.list and change squeeze to testing, then

sudo apt-get update
sudo apt-get install broadcom-sta-source
sudo m-a update
sudo m-a a-i broadcom-sta

This successfully built the module. Then edit /etc/apt/sources.list again and change testing back to squeeze and do an update:

sudo apt-get update

After a reboot the built-in ethernet and wifi both worked.

VirtualBox Link to heading

The version of VirtualBox in Squeeze is not new enough to compile against a 3.2 kernel, so just grab the 4.x release from www.virtualbox.org.

Where’s the Insert key!? Link to heading

I think it’s strange that there is no Insert key on the X121e. According to this post there are some key combos to get the missing keys:

Fn + I = Insert
Fn + P = Pause
Fn + B = Break
Fn + S = Scroll Lock

your command for installing a 3.2 kernel specifies 2.6.39?? Isn’t that a mistake/typo?

Author: carlo

Steve,

Thanks, I’ve updated the instructions to refer to the 3.2 kernel.
