Description of problem: Compiz desktop effects refuse to start on an intel core duo aluminium 20" iMac Version-Release number of selected component (if applicable): How reproducible: Install Fedora 8 on an aluminium intel core-duo based 20" iMac. Then install the proprietary driver (yum-install from livna repository the following package/updates: kmod-fglrx xorg-x11-drv-fglrx) for the ATI Radeon HD2600 PRO video card (the open source driver doesn't support this video adapter). Steps to Reproduce: 1.Launch (from gnome or kde) the "desktop-effests" window 2.Click on "Enable desktop-effects" 3.Wait for the hint. Actual results: The hint says: "Desktop effects couldn't be activated" Expected results: Desktop effects enabled Additional info: I tried also installing compiz-fusion packages for F8 from other repos, but always with the same result. No desktop effects. I always removed the previous version of compiz before installing the next one but nothing. With some packages i obtained "Segmentation fault". With others i obtained messages complaining about missing Xgl or so ...
This looks like a problem with the fglrx driver (or its configuration) you have to contact AMD/ATI for help. This is proprietary driver and therefore we cannot fix it.
