Title:
  Brightness FN  keys Not working - Dell

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The Brightness FN keys (fn+f4 and fn+f5) once pressed don't generate
  any `evdev`, this happens on some Dell laptops like Inspiron 14z
  (N411z), Dell XPS 13.

  It has been reported in the past but the old bugs look abandoned.

  This functionality was working fine before and according with old bug
  report was probably introduced with Ubuntu 13.04.

  Any chance to get it fixed/reverted ?
