The brightness control doesnt work on a Dell XPS 13 Ultrabook.
Keyboard function (FN + F4/F5) doesn't work, also the brightness control of
power mangement e.g. in KDE doesn't work.
I need to manually set
echo 0 > /sys/class/backlight/intel_backlight/brightness
then everything is fine until next reboot or suspend/resume.
