Update: Some days before, I have upgraded to Debian testing/Jessie. But xserver is still crashing during start process. But I could shut down my notebook when pushing power-button, which did not work, before. During the upgrade the following xserver packages have been installed/upgraded: - xserver-xorg-input-vmmouse:i386 (12.9.0-1, automatic) - xserver-xorg-input-mouse:i386 (1.7.2-3, automatic) - xserver-xorg:i386 (7.7+3~deb7u1, 7.7+3) - xserver-xorg-video-all:i386 (7.7+3~deb7u1, 7.7+3) - xserver-xorg-video-ati:i386 (6.14.4-5, 7.2.0-1) - xserver-xorg-video-fbdev:i386 (0.4.2-4+b3, 0.4.3-2) - xserver-xorg-input-all:i386 (7.7+1, 7.7+3) - xserver-xorg-video-nouveau:i386 (1.0.1-5, 1.0.9-2) - xserver-xorg-video-geode:i386 (2.11.13-3, 2.11.14-3) - xserver-xorg-video-radeon:i386 (6.14.4-5, 7.2.0-1) - xserver-xorg-video-intel:i386 (2.19.0-6, 2.21.14-4) I have attached the Xorg.0.log with the backtrace to this email. After this pain, I decided to install the non-free fglrx-driver package (with this doc https://wiki.debian.org/ATIProprietary), which works for me.
