Re: X server eats CPU
I suppose nvidia engineers never run kde, libreoffice and such. I can't imagine what their test stand include, may be only compiz or xfce?
It's sad, because kde4/libreoffice are mature enough to include them in tests.
It's not only about kde, it's also about firefox and chrome. Both are suffer from slow tab switching.
The cure for firefox is "nvidia-settings -a InitialPixmapPlacement=0" and cure for chrome is "nvidia-settings -a InitialPixmapPlacement=2".
Knowing this only thing I can suppose -- nvidia team use only one browser all the time (dunno, FF or chrome) and never test with other.
And this make me sad and when I see Linus trolling and I'm almost on his side, just because nvidia not only refuses to support bleeding-edge Optimus, but also breaks day to day experience with plain regular browsers, office suit, desktop environment.
