toshiba satellite 1366x768 display prob.

[Capricorny]

nvm. fixed my own problem. click Preferences, CompizConfig Settings Manager, General Options, Display Settings, then under Outputs it had the wrong resolution, so i changed it to 1366x768+0+0 and restarted the 3D desktop compiz. problem solved.

Great that you found out this yourself and reported it here!
I just want to remark that starting with cheat code no3d may be helpful with display problems. In your case, it could maybe have given you an indicator of the culprit (Compiz resolution settings). There are lots of problems reported with Compiz, but maybe most of them are due to wrong display settings?
