Boots to Bash shell after install of ATI graphics driver. How do I fix?
 

After installing the ATI graphics driver that was suggested under System > Devices, ubuntu required a reboot. now it either hangs on boot, or boots into the Bash shell. I tried the option in the Grub boot llist to boot into recovery mode, and then teh option to fix recent update (or something like that), but it did not help.
Assuming the ATI driver is the problem, how can I back it out?

You acn use your Ubuntu install disk to boot system and repair.

The desktop version gives you gui.

Thanks, I managed to get in and disable the video driver ( my memory was wrong - it was not ATi, but nvidia accelerated graphics driver)

I was able to boot to recovery mode, then selected failsafex, which allowed system to boot up using a default video driver. Once in x windows, I was able to disable the nvidia driver.
