Hi
Maybe a shot in the dark, but have you
installed the 3d driver. Can you type "sudo envy"
My screen was set to the wrong refresh rate until I installed the Nvidia Driver,
giving green horizontal bars.
Could you post the specification of your system please?
Have you tried "sudo dpkg-reconfigure xserver-xorg"
Regards - Nick
