Installed Ubuntu 12.04 today and my problem is that when I'm moving the windows around my screen it doesn't feel smooth at all. Usually I can fix this by changing the refresh rate to 60Hz, but this time it doesn't help.
My graphics card is a Nvidia GTX 560Ti and I've tried both the 295.40, 295.45 and 304.43 (which I'm currently using) but neither has resolved my problem.
I searched around a bit and tried changing the refresh-rate using compizconfig-settings-manager and xrandr. No change using CCSM, but when I tried xrandr I got this reply:
konsolkongen@konsolkongen-desktop:~$ xrandr -r 60Rate 60.0 Hz not available for this size
- which is nonsense of course.
This is what my xorg.conf file looks like:

Any help would be greatly appreciated, my obsession with video quality can't stand stuttering like this. For what it's worth though, I don't have any screen tearing, so at least V-sync is on.
Thanks.
