I was having similar symptoms, and Michel's patch at https://bugs.freedesktop.org/show_bug.cgi?id=9816 fixed it.
I didn't have nearly as many warnings/errors in my xorg logs a Felix, though (I only had the "Mode pool is empty" warning). Could he be having kernel problems as well? Some of those warnings looked like there could be pci issues. -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.21-2-686 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages xserver-xorg-video-ati depends on: ii libc6 2.5-11 GNU C Library: Shared libraries ii xserver-xorg-core 2:1.3.0.0.dfsg-6 X.Org X server -- core server -- Eldon -- If entropy is increasing, where is it coming from? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
