OK, maybe I jumped to the loginGUI-related 26D too quickly. Let's try again:

Looking through the list archive, it seems to be possible to get
srss 4.1 working on Opensolaris 2009.06 on x86 with some tweaking.
However I still have some trouble with this. i got this working on
2008.5, but just recently upgraded to 2009.06. I've reinstalled srss
4.1, and tried the tricks I've found here, but no success.
Upon reboot, sunrays are found and entry in Xserver looks like
:5 SunRay lo...@none /etc/opt/SUNWut/basedir/lib/utxsun :5 -nobanner
Which is the same as my sparc solaris 10 host.
Client then hang with a 26D error.
Doing a cold utrestart Xserver-file look like
:12 SunRay local /usr/X11R6/bin/Xnewt :12
but there is no Xnewt in /usr/X11R6/bin and clients still stops on
26D.
This looks odd, but is actually nothing to worry about. Xservers isn't
used by any part of OpenSolaris, it's just bookkeeping for SRSS and
obviously there's some sloppiness about some of the bookkeeping that's
not essential to the system operation. We actually only care about which
displays are in use by gdm and which by NSCM (i.e. "RESERVED" entries in
Xservers).
The control of gdm is via the gdmdynamic program, not the Xservers file.
We always use the utxsun wrapper when interfacing with gdm (see
/opt/SUNWut/lib/xmgr/gdm/notify).
I tried to symlink to the Xnewt binary, or use a script like utxsun, but
no success, Anyone have any clues on what to look for?
Don't pursue this route, it's a dead-end.
Is there an Xnewt process running?
What do utwho -c and gdmdynamic -l report?
Do you see anything interesting in the files in /var/log/gdm (obviously
:0 is uninteresting)?
Attached is a script I wrote to highlight inconsistencies in the
operational state of the system in cases like this. Try running it as root.
If any Linux jocks want to take a crack at porting this to Linux that'd
be great. I've been unable to find anything on Linux similar to "pargs"
on OpenSolaris that can actually show me the current environment of a
running process (ps ewww only shows the environment that was inherited
by the process, not its current environment, and I haven't managed to
get what I want out of /proc yet either). We need to see the current
environment value of $DISPLAY to deduce which display an Xnewt process
is managing.
