  IMPORTANT: Information in this "desciption field" is incorrect. Please
  read the comments for further explanation.
  
  When I close the lid of my laptop, X "hangs" when I reopen it. The
  desktop is visable, but I cannot move the mouse-pointer or use the
  keyboard.
  
  While searching though the known bugs in LP, I came across #138256. I
  followed the instructions there, but noticed that when  "Automatic
  Login" is enabled, the issue still appears. By setting "Automatic Login"
  to disabled, I resolved the issue, the instruction in #138256 weren't
  needed.
  
  If you have enabled "Automatic Login" (System -> Admin -> Login Window -> Security), follow these steps as workaroundl:
  * Add `Option "ForceEnablePipeA" "true"` in xorg.conf (as destribed in #138256)
  * "Control-Alt-Backspace"
  * Enter credentials
