Well I definitely know very little when it comes to X.
I don't have xdpyinfo
as far as I know (it seems to be a Unix thing, I am running VMS 5.4). Exceed
offers the following settings for the server visual:
xdpyinfo is a standard X11 client. I would be very surprised if it
wasn't on VMS, assuming you have the X11 client programs built for VMS
and installed.
Clearly that last entry is of some significance! I
found a definition of
decwblue and added it to the Exceed rgb.txt file. With that I got a colour
logo. However I still get a horrible fine-grained black and white pattern
for the background, rather than a smooth colour as shown here:
http://toastytech.com/guis/DWlogin.gif. It is the background you get when
you start the X server and before a client has connected. There don't seem
to be any errors related to that though.
Usually this stuff is configurable with scripts. Last time I ran X11
regularly in the early 90s I had scripts that changed the background
of the login screen. DEC has probably customized their standard login
screen in a similar fashion.
There is also an error in the log above reading a
font, is the font supposed
to be on the X server or downloaded from the client?
The font database is maintained by the server. In X11, fonts are
never on the client.
After I got the colour logo, I then logged in and got some other errors in
the log too:
3 > OpenFont: decw$cursor
3 < C:\Program
Files\Hummingbird\Connectivity\11.00\Exceed\Font\misc\deccurs.wff
Warning: Access refused on ChangeHosts request based on security setting in
Xconfig.

Xconfig.

Not sure what ChangeHosts means and what the implications are.
It looks like your initialization script is attempting to do xhost to
add hosts to the list of hosts to be trusted by this X server. See
<http://www.netadmintools.com/html/xhost.man.html> This is the "old
school" way of doing security with X11; I think they now have a
public/private key pair based way of doing things.

This (unfortunately) isn't the case anymore. There's a big trend
nowadays toward moving font handling into the client. This is a bad
idea for a bunch of reasons, but there's just no convincing the GTK
crowd of anything. The results are gorgeous, but heaven help you if you
try to run an X client from a few hundred network-milliseconds away. I
regularly run X clients in Wisconsin and display them in Florida...thank
heaven that stuff isn't using client-side font handling!

Yes, xauth. Xauth has been around for about twenty years, though;
it's just that it's sometimes not used because it's a pain in the butt.
There's also a standardized method to use Kerberos 5 to authenticate
clients to X servers, believe it or not!
