Is it System settings -> Enable desktop effects [no > check]? ..that should have it off, but it could still be trying to software rendering in the cpu rather than in the GPU hardware where we want it. ..with the default(?) setup, your "kicker" plasma tool bar should be black as you kill compositing. ..if killing the tick doesn't kill compositing, try pile up a few different web browsers and point them to some trashy flashy sites to blow up the load, that works for me and even requires logging out and back in to get the trashy eye candy going again if you want that, if you don't, just stay in and enjoy the speed. ;o) > I am currently running with no /etc/X11/xorg.conf.

I'm happy with pink holes wherever the radeon driver support might stall, but I'm not laid back enough to enjoy watching grass growth outpace my Konqueror sessions. -- ..med vennlig hilsen = with Kind Regards from Arnt... ;o) ...with a number of polar bear hunters in his ancestry...
