How to configure graphichs errors n become terminal

# remove fglrx packages
sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists)
sudo apt-get remove --purge fglrx*

# remove and reinstall the open source driver
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati

# replace lingering proprietary libraries with the open-source versions
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

Oh here's how I had to get it working:
1. Remove the 2.6.35 kernel, as fglrx crashed during the installation of the kernel
2. Restart and boot to the normal 2.6.32 kernel
3. Remove fglrx, fglrx-amdcce (some name like that) and one other package, automatically removed with fglrx
4. Tried running /usr/share/ati/fglrx-uninstall.sh - it would error out, so I had to remove /usr/share/ati
5. Reboot in safe graphics mode
6. Remove /etc/X11/Xorg.conf*
7. Reinstall fglrx, which ran dkms to update the kernel
8. Run sudo aticonfig --initial
9. Reboot
10. Enable composition - System -> Preferences -> Appearance -> Visual Effects -> Normal

sudo update-grub reboot.

to confirm you are running the new kernel type in a terminal:

uname -a
