They mention windows moving too slow and talk a lot about 2D
acceleration (XXA, EXA, UXA). But I agree, they focus on the technical

I'm not using KDE. At least Compiz refuses to start when it finds
some blacklisted graphic card models.


I was thinking about to switch from Gnome to KDE as Qt works much
better with my 845GL than GTK but then decided to get a cheap Nvidia
graphic card instead.
