Is this still a problem? If it's so, shouldn't this bug be fixed via a
"conflicts" in the packages of both the open source and the proprietary driver?
Otherwise, jockey could deal with the driver situation in a more automatic way.

Title:
MASTER: xserver crash, performs poorly, or other severe problem when
loading the radeon driver if -fglrx has not been properly removed
first
Status in “xserver-xorg-video-ati” package in Ubuntu:
Incomplete
Bug description:
[Problem]
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 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.
When launching the X server by hand I have this message:
(==) Using config file: "/etc/X11/xorg.conf"
Backtrace:

The message is the same if I choose the driver "radeon" or "ati". The graphic
