Fabio, What do you mean by 'repackage' the 8.36.5 fglrx drivers and then updating them? Do you mean the kmod-fglrx package or the xorg-x11-drv-fglrx package. I was under the impression that the 2.6.21 kernel required changes in 8.36.6. Are you even running the fglrx drivers with the necessary kernel module loaded? I assume there are two possibilities here... 1) Leave kmod-fglrx-8.37.6-1.2.6.21_1.3194.fc7 installed (which doesn't seem to show an error when loading) and hope that the xorg-x11-drv-fglrx-8.37.6-1.lvn7 can properly load with the older xorg-x11-server-Xorg package installed. 2) Install the older 8.36.5 xorg-x11-drv-fglrx package and rebuild the kmod-fglrx package for that release. Thanks in advance for any clarifications. Jack
