Title:
  [Dell Latitude 6430u] Brightness keys do not work

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Running 12.04.2 on the system and the brightness keys do not work.
  The keys are a combination of Fn and Up or Down arrow.

  On attempting to use the keys, there is no effect on screen
  brightness, nor is there the brightness indicator.

  However, I am able to control brightness using the Brightness settings
  from "System Settings"
