[Dave Lindquist <821749@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

On an unpredictable basis (from twice per day to once a week), my login
session simply stops 'drawing'.

Most often, this happens when waking from screensaver -- I attempt to
wake from screensaver, and the screen stays black (the screensaver is
'blank screen').  However, moving the mouse around, the mouse pointer
correctly changes arrow and text cursor shapes when moving over the
'correct' locations for entry of password on-screen.

Ubuntu 11.04
Unity 3D interface (default)
Intel Sandybridge system (sandybridge graphics)
xorg 1:7.6+4ubuntu3.1

Latest updates all installed.  No 'funky' software (for example, dock
software, etc).

Oddly enough, if two sessions (two different users) are logged in, the
Ctrl-Alt-F8 keystroke will switch to the second session, which will draw
correctly.

Remotely doing a kill of the correct gnome-session will 'log it out' in
some semblance of normality, and begin drawing again.  (i.e, I can log
in on that same vt with no problems).

This has also happened at least once on login -- i.e., I'm stuck at the
logging in graphic, but the mousepointer changes when going over windows
that have 'opened' invisibly.

Is there anywhere I could look for further information in debugging
this?

My /var/log/Xorg.0.log.old gives this at the end (the VT switch will be
me hitting Ctrl-Alt-F8, likely), the rest is likely my kill of gnome-
session:
