Public bug reported:

Binary package hint: xorg

This past friday, I rebooted by ubuntu system. It came up and I was able
to log in, but the screen was not rendering properly. The unity menu on
the right was basically invisible, the top menu bar was not rendering,
the entire screen was hazy, and there were other artifacts on the screen
that arent supposed to be there.

I suspected that the cause of the problem was caused by one of the
xserver packages. I noted that xserver-xorg-core and xserver-common were
updated that Wednesday from 2:1.10.1-1ubuntu1 to 2:1.10.1-1ubuntu1.1. I
downgraded to the previous version of these two packages and rebooted.
Same thing. Then I rebooted again and the problem seemed to have gone
away. At this point, I was somewhat confident that I could resolve the
problem if it happened again so I upgraded those two packages to there
most recent version. The problem occured again, but this time
downgrading didn't help, which was bizzare. I reinstalled ubuntu and
then explicitly didn't allow the xserver-xorg-core and xserver-common
packages to be upgraded. Everything was fine for the rest of the day but
that evening, the display froze. I rebooted to recover and the problem
came back.

I have reseated the graphics card but that didn't help. I also noted
that I was able to use the "Ubuntu Safe Mode" session in GDM and the
desktop looks fine. This leads me to believe it is  a problem with the
unity interface, or some 3d code that gets invoked when I'm running in
normal mode.

So the specific sequence is:
- boot computer - things look fine on the screen
- gdm runs to collect login information, things look fine on the screen
- ubuntu desktop appears  but rendered improperly. artifacts appear on the screen

I am filing this bug from safe mode so I'm not sure if the logs captured
by it will have the relevant information. I do have Xorg.log from when I
ran in normal mode and saw the problem and can attach that if necessary.
