Keyboard backlight

Note: Not all X250 keyboards have backlight

In order to get the backlight to work, add 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 xorg-xbacklight as well as enable some of the extra media keys.

Audio

In order to get control of the audio from Intel hdmi, you have to disable it and force alsa to use Intel PCH. See ALSA#Set the default sound card to set the default sound card to Intel PCH (speakers and headphones).

/etc/modprobe.d/thinkpad-x250.conf
options snd_hda_intel index=1,0
