If X is actually crashing, there should be a backtrace at the end of
/var/log/Xorg.0.log (or log.old if X already restarted since then).
It would be even better if you catch a backtrace with gdb after
installing xserver-xorg-core-dbg and libgl1-mesa-dri-dbg. Since your
machine seems to be alive after the problem, logging through ssh and
attaching gdb should be easy.

Beware of this. Assuming this is th X log after a soft reboot after the
crash, it may mean that the hardware didn't get properly cleaned,
causing some possible problems later. A hard reboot after the crash may
help.
