Updated on my daughters dual boot machine because she was not using it. Thought Compiz might impress, I am having difficulty with setting up a ATI Radeon 9800XT card and 1680*1050 LCD monitor. The pre desktop config doesn't work and neither does 'Screens and Graphics'. Above kit just works in XP.

On my machine I run nvidia and have managed to get Compiz working with it. I recall using nvidia-xconfig to get it going. Is there a similar thing with ATI?
