Title:
  Ubuntu 14.04 blank screen after wakeup from sleep

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  Possibly related to bug 1283938 . I have disabled lock screen on
  suspend to try and get around the bug but it obviously hasn't worked.

  I see a completely black screen with a working mouse cursor.  Used
  Ctrl-Alt-F2 to login at a text terminal and tried to kill gnome-
  settings-daemon and gnome-shell (doing so has randomly made it work in
  the past).  The gnome-shell process would not kill and I got segfault
  dmesg errors which are attached.
