Yesterday I upgraded the system and came the same error, unity and compiz does't work. I uninstalling fglrx and now my screen does't work anymore, everything is black. I listening the ubuntu initial sound, but my screen still black. Because of this problem I thinking if I install 12.04 or change distribution to another. None of the solutions presented solved, only worsened. Ubuntu 12.10 + ATI 46xx does't work.
