I had an issue with my video card not rendering dual monitors correctly so I attempted to remove and reinstall the fglrx drivers. I followed these steps.
FglrxInteferesWithRadeonDriver
sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists)
sudo apt-get remove --purge fglrx*
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 libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
After following the instructions on this page I am left with no video. After boot the screen goes blank and the signal drops to the monitors. How can I get this fixed?
chroot in to your environment from the Ubuntu Live CD, blacklist fglrx in /etc/modules/ go get an Nvidia based card. I hate my 5770 in to the deep reaches of outerspace. I've got it working, but not particularly well. Many Pandas are crying. – James T Snell – 2011-10-05T01:58:00.973
I explain chrooting fairly well here - just take your own route after Step 4.

Well, if you want to get your machine in to a remotely workable state, then try the first half of my suggestion. – James T Snell – 2011-10-05T03:48:06.363
