has anyone succeeded in getting KDM work work with XDMCP requests in RH
Enterprise 4?
I can get GDM to respond just fine, but not KDM (and I need KDM for various reasons)

Do you have XDM enabled in /etc/X11/xdm/kdmrc ?

XDM ???
I have XDMCP enabled in kdmrc
(as far as I can see from my GDM chooser log, KDM never responds when it gets a
request for a login manager, it does respond to chooser broadcast, but nothing
happens when I click the server entry in the chooser, at least nothing other
than a gray display)

Hey Lars,
Yea... XDMCP is what I meant.
I've been playing around with this issue trying to duplicate the
results you're getting and I may have it figured out.
If your /etc/sysconfig/desktop file doesn't include both of these
lines:
DISPLAY=KDE
DISPLAYMANAGER=KDE
You will end up with the results you described.

Nope doesn't help, I still get a gray screen as usual.
currently /etc/sysconfig/desktop contains this:

Damn.
Well, other than that the only other file you should have to check is
/etc/X11/xdm/xdm-config
and make sure the last line (DisplayManager.requestPort:0) is commented
out.

This is a real head scratcher.
Have any changes been made to /etc/X11/prefdm?

. /etc/sysconfig/desktop

If you run:
ps aux | grep kdm
does it show kdm running at all?
If not try running kdm as root in at the console and then see if you can
get a remote connection.

kdm runs just fine, when ever I do a direct request for it in the GDM
chooser on my terminal, it shows up fine in the chooser, which means
that kdm is answering, but if I choose it in the chooser I just get a
gray screen.
(we're using LTSP based terminals, and several servers people can choose
from)
