It hanged yesterday twice, today once. This time the $ ls -l /var/log/Xorg.0.log -rw-r--r-- 1 root root 40724 2008-01-04 09:14 /var/log/Xorg.0.log is filed with binary zeros.... I think the severity of this bug should be raised, what do you think? Maybe the problem is not in the xserver-xorg package, but clearly the bug renders the computer unusable, and clearly, there is a bug somewhere. Ondrej
