I'm not too familiar with proprietary driver installation on Linux. I used to just use the old OSS drivers but due to more demand for performance I switched. I've been using AMD GPUs (no flame war intended, so please refrain from the urge...) for nearly my whole life on both WIndows and Linux, but on Linux, uninstalling drivers to install new ones isn't as easy as it is on Windows, obviously.

So what is the 100% foolproof way of uninstalling the Catalyst driver (in my case, Catalyst 12.11 beta 11) and then having it be barebones again so that I may install the new one that apparently just came out, Catalyst 13.11?

Can someone give me the absolute answer? Everything I've seemed to find online just makes my terminal report back with "No existing blah blah blah" and stuff like that.
