The touchpad and TrackPoint work out of the box, but the physical buttons for the trackpoint do not. You will need to install.
If you would rather not install a recent kernel, there is a work around for Linux 3.19.2-ARCH. If you add
options psmouse proto=imps to
/etc/modprobe.d/x250.conf, you can force the mouse module to use a more basic protocol than the built in one for the TrackPoint, which needs a patch. The effect is that the touchpad and mouse are treated as one device, but synaptics is not supported. If you want two finger scrolling, for example, you will need to either deal with the broken TrackPoint buttons are install the new module.
The fingerprint reader works out of the box with.
Backlight and Keyboard
In order to get the backlight to work, I added
options thinkpad_acpi force-load=1 to
/etc/modprobe.d/x250.conf. This forces the thinkpad_acpi module to load, which is needed for controlling the backlight via as well as enable some of the extra media keys.
Sound and Volume Control
Withand installed, you can map the volume buttons to change the volume. Here are some samples:
event=button/mute action=amixer -c 1 sset Master toggle -q
event=button/volumedown action=amixer -c 1 sset -M Master 5%%- unmute -q
event=button/volumeup action=amixer -c 1 sset -M Master 5%%+ unmute -q
event=button/f20 action=amixer -c 1 sset Mic toggle -q
PulseAudio and are also great tools for fixing volume issues.
