Bug Description
I have a fully updated Ubuntu 12.04 x64 installation with Nvidia driver 302.17 enabled. The system contains an NVIDIA GeForce GTX 460 video card.
The problem I notice is that hardware acceleration stops some while after log in. Immediately after reboot, GLXgears reports up to 3000 FPS. After a few minutes to hours, hardware acceleration stops, which is e.g. noticable by a sluggish response from the user interface. E.g. typing an e-mail becomes impossible, since the letters appear too slow on the screen. Re-running GLXgears in that case reports about 23 FPS.
I noticed that the problem does not occur if I keep GLXgears running on the background. I can't find any unusual things in /var/log/xorg.0.log that give hints about what is happening during the occurance of the error.

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.
