Tom, thanks for your reply. Actually that video showed the "best performing" session I've had with karmic :(
Anyway, the CPU consuming is ** at least 25% ** when no other programm is running, beside system daemons. Executing Firefox, for example, maked Xorg consume up to 80% till 100% of CPU. I would exclude any Firefox influence: the problem persist even if I run Goolge Chromium, just installed it. So, what to do? Open a new bug report? Declare this as duplicate of another bug?
