Bug Description
Recent updates to 12.10 have caused a regression of bug 931967. This is reproducible on my MacBookPro 3,1 with NVIDIA 8600M graphics.
To reproduce:
1) Cold-boot
2)Enter username and enter password at the greeter (login prompt); press enter to login
Expected results:
After entering the password, there should be a transition to the desktop. The transition might include a black screen for a moment.
Actual results:
After entering the password, there is full-screen corruption for a second or two until the desktop is drawn. The corruption looks like the system is displaying uninitialized memory.
See bug 931967 for an example screenshot.

Your system is not currently configured to drive a VGA console
on the primary VGA device. The NVIDIA Linux graphics driver
requires the use of a text-mode VGA console. Use of other console
drivers including, but not limited to, vesafb, may result in
corruption and stability problems, and is not supported.
