Status in HWE Next:
  Incomplete
Status in xorg package in Ubuntu:

Bug description:
  Failed to adjust brightness.

  Unable to change brightness with hotkeys or even system settings.

  Additional information:
  There are two backlight interfaces and the system seems to use the wrong one.
  /sys/class/backlight$ ls
