error (pid 20670): Server for display :0 can't be started.
This box is headless.. (and was when it wasrunning Sun Ray Services 4)..
are the device errors a config problem or an artifact of being too old a
version of X?
config problem - no newer version of X can come up on a non-existent
graphics card either, you just need to change the dtlogin or gdm configuration
to tell it not to bother trying to start a :0 X server on the graphics card
that's not there.
Note that GDM cannot be configured to not start a display on :0.
But then if he was running GDM he wouldn't be getting errors in
/var/dt/Xerrors - that's dtlogin only.
GDM logs errors per-display in /var/log/gdm/.
None of which is relevant to the problem he's seeing, unfortunately.
I'd verify that there's an Xnewt process running for his display. The
display can be determined by utwho -a.
If not, since there's no error in the log, I'd use coreadm to direct
global core dumps to someplace like /var/core/ and see if Xnewt is
dropping core files. If so, a pstack on the core file could be helpful.
Sometimes it can be useful to capture errors from /opt/SUNWut/lib/utxsun
(which launches the X server) someplace. To do that, add a couple of
lines near the top of the file like:
----
exec 2>/tmp/utxsun.$$.out
set -x
----
-Bob
