Can you still log in via ssh at that point?

Please attach the Xorg.0.log file and the output of dmesg. Preferably from
after the problem occurred, or if that's not possible, from before.

Yes. SysRq still works, too.

Looks like the X server may not shut down cleanly. Is there something
interesting in its stderr output? You may find it in the display manager log
file(s).

What happens if you try starting X again or switching VTs using chvt from ssh?

I redirected the output of startx to a log file, but
there's nothing interesting in there AFAICS.

Sorry, I just assumed that ssh would work because the machine
still responds to SysRq input. I cannot test this ATM.

I don't think the stderr output of startx captures the stderr output of the X
server. Please manually start just the X server itself and redirect its stderr
output instead.

Why -configure? You want to run the X server, not configure it. :)


What I'm looking for, but not seeing, is this line at the end of the X server
shutdown:

 (EE) Server terminated successfully (0). Closing log file.

So it seems like the X server either dies uncleanly for you, or hangs during
shutdown. In the former case, there should be more information in the X
server's stderr output. The latter case will be hard to debug without ssh
access I'm afraid.
