Hi everybody! I've changed some hardware coupple of days ago .Now I'm using ATI Radeon X1800XL.I've compiled and installed the latest drivers for this card on Ubuntu 7.10. fglrxinfo gives back: 3D acceleration works to.What next steps do I need to take to make Compiz Fusion work ? I've tried to enable it (thru preferences) without luck. I only get "Desktop effects could not be enabled.". Also entering compiz --replace in the terminal returns: Things are more complicated with Ati cards in comparison with nVidia. Information found on Google didn't solve my problem so I hope someone here has some experience and could advise me what to do. Thanks!
