Hello, and thank you in advance for helping me.

I am currently running ubuntu on a sony VGN-A790. It has an ati mobility radeon x600. I have been having an issue with any full-screen games. My screen will look weird and then slowly fade to white whenever I open a game full-screen. The Hardware Drivers under System > Administration > Hardware Drivers says that there are no proprietary drivers in use. It will let me enable the extra effects if that helps. I think getting a different driver for the graphics card may fix this problem

I am rather new to linux and any help is appreciated.
