sorry I worded that badly.
I can install nvidia drivers fine from the restricted drivers module, also I can use envy. Both work fine, with no errors.
Also I can play 3d games fine, as long as they are in 1024 x 768 or lower resolution. The native resolution of my lcd is 1280 x1024.
When I set games to run at 1280 x 1024 it appears in a window, I can still see the start bar and mouse cursor, and the mouse is frozen, however the game continues to play with the keyboard, so it is not frozen. Manually editing the resolution in the game .cfg files doesn't seem to help.
Also I have tried it on many games, with the same results.
Thanks so much
