Here's the followup for the comment #41. I was able to reproduce the problem and the temporary fix: http://www.youtube.com/watch?v=_cOiSYYFOi4&feature=youtu.be

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. --- .proc.driver.nvidia.gpus.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86_64 Kernel Module 302.17 Tue Jun 12 16:03:22 PDT 2012 GCC version: gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) .proc.driver.nvidia.warnings.fbdev: Your system is not currently configured to drive a VGA console on the primary VGA device.
