[Launchpad Bug Tracker <900308@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

After being suspended for a weekend (Friday pm to Monday am - about
60hrs) Unity/compiz (or X?) reliably crash upon resume, dropping me to
the lightdm greeter. As a result whatever apps I had on my desktop are
gone - it is as if I had restarted or logged out. Shorter periods of
sleep work fine; the machine resumes normally after being suspended for
1hr.

I believe this is a regression that appeared a couple weeks after 11.10
(I regularly pull from oneiric-proposed) but I don't have an exact date.

I haven't found any indication of a crash in any system logs, and there is nothing in /var/crash/.
I do see this at the end of /var/log/Xorg.0.log.old:
[121316.041]  ddxSigGiveUp: Closing log

In the attached logs, I put the machine to sleep on Dec 2 at 17:05 and
woke it up on Dec 5 at 08:53.

To reproduce:
1) Suspend the machine
2) Unplug it so it's running on battery power
3) Don't touch the machine for a few days (Friday night-->Monday morning, for example)
4) Plug the machine back in and wake it up

Actual results:
1) After the screen comes on, I see the desktop background and a few flashing white rectangles that correspond to windows on the screen (same size/position).
2) X seems to crash/quit; I see a console with text (no screenshot available, sorry)
3) Light starts and I'm prompted to login

Expected results:
Machine resumes to the desktop


Hardware is a Macbook Pro 3,1 w/ NVidia graphics. OS is Ubuntu 11.10 AMD64. I upgraded to nvidia-current-updates 285.05.09-0ubuntu0.1, but that did not solve the problem.
