I'm trying to install "amd-driver-installer-catalyst-13.1-linux-x86.x86_64" for my HD 7850, but I'm having issues getting my old driver uninstalled (which I got from "fglrx-updates" under software sources). I followed the instructions in "How do I remove the FGLRX drivers after I've installed them by hand?", but once the second command finished, the drivers were still detected by the installer I first mentioned.
Would I need to restart or use an entirely different command? The last thing I would want to do is screw up my graphics.
