--- Comment #11 from Michel Dänzer michel@daenzer.net --- (In reply to comment #8)
When I run "sudo Xorg -configure" I get:
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.
