I gave up on using ATI video cards in my Ubuntu machines. ATI does have a proprietary driver you can get, but I experienced a ton of problems on 8.04 and 10.04 with it, and the generic ATI drivers weren't much better. I ended up, like Jon mentioned below, with an nVidia card and my problems went away.
