** Description changed:

  Binary package hint: compiz
  
  Often (although not always) in natty when I resume from suspend and type
  in my password at the (correctly-drawn) gnome-screensaver unlock screen,
  I continue to see the unlock screen.  My mouse cursor changes shape as I
  move it around the screen, but nothing else happens.  If I switch to a
  different VC with Ctrl+Alt+F1 and switch back, I see the picture of my
  virtual console framebuffer instead of the unlock screen -- but mouse
  cursors changes shape according to what GUI controls are underneath it,
  indicating that I'm looking at X.
  
  The fix is to killall -9 compiz in the text console.  Unity respawns a
  new compiz process and I can continue to work normally after switching
  back to the X virtual console.
  
  I've integrated Intel 965 graphics, and I don't remember this ever
  happening in Maverick.
  
+ ----- update ------
+ 
+ This bug happens with compiz git master as well though it seems it starts
+ working after waiting for a few minutes. The amount of time the display has been asleep seems to be proportionate to how long you have to wait before
+ compiz 'snaps out of it'. I suspect this could possibly be related to glib
+ timers being broken.
