Hi, Could you try the latest xserver-xorg-video-intel package (2:2.0.0-5 currently in experimental) and report back whether it fixes your problem? If it does not, it would be good to catch a debugging backtrace with gdb. You'll have to install xserver-xorg-core and rebuild xserver-xorg-video-intel with debugging enabled (look at http://wiki.debian.org/HowToGetABacktrace). Thanks, Brice
