[Daniel van Vugt <daniel.van.vugt@xxxxxxxxxxxxx>]

** Description changed:

  The issue appears to be that radeon's implementation of
  glXWaitVideoSyncSGI (from libgl1-mesa-glx) hangs and leaks X events
  while the screen is locked and asleep. The leak is around 200 bytes (one
  XEvent) per frame or about 12.5KB per second.
  
  It is most noticeable if some application is continuously redrawing during this time. But only if the application itself does not sync to vblank. For example: KVM, QEMU or:
-     env vblank_mode=0 glxgears
+     env vblank_mode=0 glxgears
  
  WORKAROUNDS:
  
  1. Before leaving/locking the PC run ccsm, and in the OpenGL section
  disable "Sync To VBlank".
  
  2. Before leaving/locking the PC, minimize all active windows.
  
- 3. Install fglrx driver from AMD/ATI.
+ 3. Install fglrx driver from AMD/ATI. But then you'll have bug 969860.
  
  ORIGINAL DESCRIPTION:
  There are two issues.
  
  Compiz has a memory leak so it expands to take up all memory plus swap
  (12 + 4 gig)
  
  Unity shows a blank screen and does not come up with a login prompt,
  only the mouse pointer is displayed.
  
  ctl+alt F1 works so you can get into a console and create the attached
  bug report.  This was after killing vviewer and before restarting
  lightdm
  
  I was running KVM and vviewer as well and killed vviewer but still did not get get login screen
  Killed compiz which freed the memory still did not get login screen
  had to restart lightdm to get back into Unity and restart everything.
