Thanks for the response. I did not try connecting to the
machine with ssh (like telnet). I did try
Ctrl-Alt-Backspace, but like in your case it did not work.
This may be the case but I don't think it is. From the
machine in question I used ssh to connect to another
machine. From that machine I used scp to copy files back to
the original. I don't think that a remote scp connection
could cause just X to crash but I could be wrong. I will
make sure to ssh to it from another machine next time it
happens to see if it is possible.
