Sometimes when I start or stop the X server, for instance at boot when GDM
loads, or when I logout of Gnome and GDM is restarted, the screen goes blank,
and the monitor shows an orange light as if it were disconnected from the
computer.
The computer is still on, but I think it is frozen, because I can't use ssh
to access it. I've diffed the Xorg logs from a normal server and a frozen server
and they are the same besides dates and other trivial lines, unless perhaps
the frozen server doesn't even write to a log. If you think I should try that
again, tell me. I could have done something wrong.
