Title:
  Cannot adjust screen brightness

Status in “linux” package in Ubuntu:
  New

Bug description:
  The screen brightness of the notebook cannot be adjusted and is stuck
  in a super low brightness.. I can barely see.

  This problem started last week and because I work with an external hdmi monitor most of the time it took me a while to notice it. 
  I am pretty positive it start after I installed the new hardware support a couple weeks ago.

  The image on the external monitor is perfect.

  hardware: dell xps 13
  ubuntu 12.04 (up-to-date) and WITH the “New Hardware Support” installed.

  What information should I provide to get help???
