We need a backtrace of the crash. You can get a minimal one at the end
of the log after the crash (in /var/log/Xorg.0.log.old if X already
restarted since then). Better would be to install xserver-xorg-core-dbg,
login from another machine through ssh, attach gdb to the X server with
gdb -p $(pidof X), reproduce the crash, enter 'bt full' and send us the
However, since you seem to be using the nvidia binary driver, it si very
likely that any above backtraces will be empty. In this case, we won't
be able to do anything about this bug unless you reproduce it with a
free driver and provide us with a backtrace.
