xsession fails on login due to video driver kubuntu 11.10

[rdesfo]

I can't login into kde-plasmoid, but I was able to log into the console and look at the ".xsession-errors" file.

I believe what caused this issue is I added the "ATI/AMD proprietary FGLRX graphics driver" in "Additional Drivers" application and then removed it. I don't think it removed it properly.

I can now log into kubuntu because I reinstalled fglrx with "apt-get install fglrx"

but when I got into "Additional Drivers" it doesn't show it as active. So there is still an issue with the "Additional Drivers" application managing drivers

I tried to download the driver from the AMD website and when it is installed it still causes a failed login.

Status changed to 'Confirmed' because the bug affects multiple users.

After last update I can not log in. Will try removing AMD propritetary drivers.

Also happened to me after removing the -fglrx propietary driver in Jockey. Fixed by purging it some more and reinstalling libgl1-mesa:

sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx:amd64 libgl1-mesa-dri:amd64 libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

sudo /etc/init.d/kdm restart # or whichever login manager you use

as per <a href="https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver#Problem:__Need_to_fully_remove_-fglrx_and_reinstall_-ati_from_scratch">FglrxInteferesWithRadeonDriver</a>.

I suspect that only "sudo apt-get install --reinstall libgl1-mesa-glx:amd64 libgl1-mesa-dri:amd64 libgl1-mesa-glx:i386 libgl1-mesa-dri:i386" was necessary, so you may want to try that first and report back.

Note that this is on Oneiric (which has multiarch enabled by default), where I had both amd64 and i386 packages installed, so I had to reinstall both or face a "<a href="https://bugs.launchpad.net/ubuntu/+source/apt/+bug/859188">E: Internal Error, No file name for libgl1-mesa-glx</a>". If you're not on Oneiric or have disabled multiarch, an old fashioned "sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri" should work.

"sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri" did the trick for me
