All troubleshooting related to X crashes starts with reading the
relevant logs, in order to see what happened.

In the /var/log directory there should be two log files, Xorg.0.log and
Xorg.0.log.old --- one of these files (probably the .old) contains the
logs of the crashed X session. My suggestion is that you recreate the
crash, and then post both files so that we can compare and see what went
wrong.

Even better (given that those files are somewhat large), put them on
pastebin or similar, and send us a link.

HTH, :-)
