crash system after atempt to install ATI driver

I try to install ATI driver from here but after successful installation and rebooting system, I catch only console and can’t start KDE ? How can I repeal this problem or anybody know how can I rollback to previous statement ?

Take a look at /usr/share/ati/fglrx-install.log, see what happened in the install attempt.

I have had good luck with installing the ATI drivers by means of the .run file on my AMD64 box, rather than the 1-click approach. Maybe that’s worth a try.

Hope this helps.
