Thanks David, thanks Zhen! I'm running the 2.6.31-gentoo-r6 kernel, xorg-server-1.6.5-r1 and x11-drivers/ati-drivers-9.11 So, this is quite recent. I've patched my xorg-server as described here http://www.mail-archive.com/gentoo-am...@lists.gentoo.org/msg11704.html
I don't run KDE and most of the time everything works just fine. Then, suddenly X takes much CPU time, the mouse gets nearly non-responsive. I have killed nearly any user process without any change. Only killing X itself cures the problem. Of course, I have reemerged x11-base/xorg-server x11-drivers/ati-drivers and I have run revdep-rebuild. Probably I have to somehow compare every lib on the "faulty" machine to another once which should have identical packages. Thanks again, Helmut.
