>From bug #315889, which had a similar root problem - fglrx bits left over from a prior install, here are some comments/notes:
With the linux-source-fglrx package installed, dkms kicks in and loads the kernel module even when -ati is used. There should be some sort of dependency between the linux-source-fglrx and fglrx-installer package so that uninstalling fglrx will take out linux-source-fglrx as well. ** Summary changed: - MASTER: xserver crash when loading the radeon driver if -fglrx has not been properly removed first + MASTER: xserver crash, performs poorly, or other severe problem when loading the radeon driver if -fglrx has not been properly removed first ** Description changed: [Problem] - Running X with the -ati driver fails with a crash if -fglrx is not fully installed first. + Running X with the -ati driver shows various problems if -fglrx is not fully installed first, including crashing, performing poorly, failing during gl operations, etc. A typical use case is upgrading from Ubuntu when you were using to fglrx, to a development version of Ubuntu where -fglrx is not available, and -ati is used instead. - -ati and -fglrx share some overlapping files, which -fglrx replaces when - it's installed and that results in -ati breakage. + -ati and -fglrx share some overlapping files like libgl, which -fglrx + replaces when it's installed and that results in -ati breakage. -fglrx + also installs kernel components which can cause problems if they're + still present when running -ati. + + For more info, see + https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver [Workaround] Make sure -fglrx is fully purged from your system 1. sudo apt-get remove --purge fglrx* 2. sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon 3. sudo apt-get install xserver-xorg-video-ati 4. Restart X [Original report] After the update to Intrepid, the X server no longer starts.
