OK, thanks for the info. I'll abandon this for now: 1. I'm new-ish to Linux and only upgrade from the Package Manager (its easier and usually works). The update isn't in it yet. 2. Its an old PC and I don't wanna spend any money on it, and its the only GPU I had to use in it. I'll either wait for the update and try then, or just remove these demo's. Thanks for your comments/help.
