This appears to have been fixed in Mesa some time by 12.10. Last time I
could reproduce it was in oneiric (Mesa 7.11) but can't reproduce it now
in quantal (Mesa 9.0). Given the comments on this bug kind of stopped
around April, it could be that the fix was released in Ubuntu 12.04 with
Mesa 8.0...
With quantal right now I can confirm that radeon's glXWaitVideoSyncSGI
no longer hangs when the screen is asleep. I see it returning regularly.
So even if no leak was explicitly fixed, the fact that it doesn't hang
at all any more could be working around any potential leak.
Next step is to find out if the bug is fixed in precise too (Mesa
8.0.4).

Title:
[radeon] Compiz memory leak and blank screen unable to login when
using radeon driver

Bug description:
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
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. 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.
