I updated my system via the package manager from Unity and next restart was just blackness. After being here: http://linux.hootip.com/amd-catalyst-12-11-beta-fix-and-installation-the-drivers-on-ubuntu-12-11/ I had the Catalyst 12.11 Beta driver installed. I checked my /var/log/apt/history.log and the update I received was of compiz and xorg packages. I tried to get latest release info, but all I get from their pages are commit info; I can't tell what was n the package update I got served. Anyone knows what was in the latest xorg/compiz release that broke the driver? Which driver should I use now?

For completeness this is how I got the system back to boot (probably lame and not elegant):

  1. Boot with GRUB selection "More Ubuntu options (or sth like that),
  2. From secondary screen select 3.5.0-19 with boot options,
  3. When system prompts on stuff you'd like to do, select "root" - Drop to root shell,
  4. There:

    # mount -o remount,rw /
    # mv /etc/X11/xorg.conf /etc/X11/xorg.conf.failed
    # /usr/share/ati/fglrx-uninstall.sh 
    # reboot
    

This got be back on my feet.
