I have a ati x800 gto2. In mepis, I tried to install the flgrx driver. Upon rebooting, I cannot access kdm anymore, it gives back errors about the driver. How can I change the display driver back to what it was originally through the command line? Or uninstall the flgrx driver?

My basic question is: How do I change the display driver back to the original settings via the command line?

I have heard something about xorg.conf, is it something to do with that?

Thanks a bunch.
