Maybe a hint to solve the problem: The desktop effects are very very slow, compared to ubuntu 10.04.

System freezes regularely and not reproducable after a certain amount of time. (from 2 minutes to half an hour) Also no particular GUI-Application causes the error. Even playing flash doesn't cause the error directly. Also from time to time, i have little freezes where mouse and keyboard are locked for a few seconds (often when starting applications) While completely frozen, i can still move the mouse-cursor, but mouseclicks do not work. Also the keyboard is completely locked. I'm not able to change to TTYs by pressing CTRL+ALT+F1-7 SSHing into machine works fine. I can restart lightdm from SSH-connected machine and i'm back to login screen (system usable until next freeze). Without having an ssh connection i'm forced to power-off with button. Didn't experience the problem with nvidia drivers (but can't adjust screen brightness using it, so it is no solution form me). Working with Ubuntu 2D works fine (no crashes so far). Can't reproduce if it started after upgrading to final LTS, because I used nvidia drivers with beta2 Logfiles (collected over SSH) attached, please let me know if i can help with other logs.
