Title:
  Screen Backlight Goes Blank and Won't Turn Back On

Status in linux package in Ubuntu:
  Expired

Bug description:
  I was working on my computer when all of the sudden the screen went
  blank like it normally would after the lock screen comes on from
  inactivity and eventually goes blank.  However, it didn't go blank
  from inactivity but instead just went blank randomally.  It would not
  resume the back light upon movement of the mouse or keyboard.  You
  could barely see the desktop and my bluetooth headphones were still
  playing the music I had in the background.  I had to do a hard reset
  because I couldn't the screen well enough to run any sort of
  diagnostics.  After reboot the screen back light started to display
  again without any problem.  At first I thought it might be a hardware
  issue but now I believe it to be a software issue.
