Title:
  Laptop screen remains blank when resuming from pm-suspend, even though
  an external display would turn back on.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Update (2014-Aug-09): An external display connected via VGA port would
  turn on when the system resumed from suspend, but the primary screen
  (and possibly backlight) remained blank.

  ------------------

  When resuming from suspend, the PC's screen remained blank. However,
  everything else seemed responsive, as I was able to log in and turn
  up/down the volume via shortcut keys and got an audio response.
