DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

If you need help to get Debian running on your hardware, please have a look at our user support channels where you may find specific channels (mailing list, IRC channel) dedicated to certain types of hardware.

Important Note

This machine was not actually installed from scratch: a working install was migrated from a x120e that was previously working, so hacks that were done at the time might be missing here.

Configuration

Display

Works out of the box.

Audio

Seems to work out of the box without problem.

Mouse

There is a known problem with the touchpad on x220 laptops, if the BIOS was updated. Here's how to tell which version you are running: 

$ sudo dmesg | grep 'Touchpad' 
[    2.130525] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps: 0xd002a3/0x940300/0x123800/0x0, board id: 1611, fw id: 1099905

Above shows the problematic version (fw: 8.1), the previous version (fw: 8.0) is apparently fine.

The symptom is that the touchpad cursor movement is "jumpy" and imprecise. The Fedora bug #1264453 has a good description and a workaround.

In my configuration, the bug was also bound to the synaptics driver, so the fix was simply: 

apt-get remove xserver-xorg-input-synaptics

Another workaround is documented in the Arch wiki and consists of this hwdb hack in, say, /etc/udev/hwdb.d/90-libinput-x220-touchpad-fw81.hwdb: 

touchpad:i8042:*
 LIBINPUT_MODEL_LENOVO_X220_TOUCHPAD_FW81=1

Then run: 

udevadm hwdb --update && udevadm control --reload-rules && udevadm trigger

Power Management

Suspend and hibernate work out of the box.

WiFi

Requires the non-free firmware-iwlwifi package.

Keyboard's hotkeys

To have the backlight keys work properly under i3, I had to do a special configuration in Xorg, otherwise the xbacklight program wouldn't work properly. Drop this in /etc/X11/xorg.conf.d/20-thinkpad-x220-backlight.conf: 

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    Option      "Backlight"  "intel_backlight"
EndSection

Then xbacklight should work, which I configured in .i3config as: 

bindsym XF86MonBrightnessDown exec xbacklight -dec 5
bindsym XF86MonBrightnessUp exec xbacklight -inc 5

This seems to work out of the box in GNOME, however, so it might not be necessary in your desktop environment.
