And here I hoped that since the last time I tried that it would finally work.. many months have passed since the last time I gave Linux a go on this desktop. The fact that you're saying that you're still having this problem now is not making me feel any happier.

... if in the next 6 months the situation doesn't get any better I feel I am going to physically destroy the GPU with a hammer, send the pic to AMD and buy a nvidia before the need for a hardware upgrade even shows up. The fact that it has drivers problems even under windows doesn't help making AMD's case.
