Title:
  Black Screen When Recovering from power save mode

Status in xorg package in Ubuntu:
  Expired

Bug description:
  Occasionally, when I recover from power save mode I get a black screen
  with just a cursor.  I can't see the desktop or any applications but,
  according to ps, they are still running.  I have to kill X to recover
  from this bug.

  Currently, I am running KDE using GDM but it has happened to me
  previously using Unity and lightdm and Unity and gdm.  I am running a
  two-monitor setup.  One is connected via displayPort and the other is
  DVI.
