You have the proprietary fglrx/Catalyst driver installed. It no longer supports your GPU ( bug 1058040 ) Purge the fglrx package, make sure you have no /etc/X11/xorg.conf file, and restart your computer.
If you continue to experience problems after removing the fglrx/Catalyst driver, please file a new bug.
