Description of problem:
Recently on F-8 GDM stopped appearing in a vncts-ltsp-config xinetd started vnc
session. The session starts fine, but in the vnc window i just get the
black/white checkring that you normally get just before GDM starts. GDM doesn't
start and present me with a login screen.
Version-Release number of selected component (if applicable):
[same versions on both server and client - both fully updated F-8 nistalls.]
Steps to Reproduce:
1.install vncts-ltsp-config on server, and start xinetd service
2.on local client do vncviewer -FullColour -via server.address.com localhost::5900
vnc session starts, but the GDM login never appears.
vnc sessions starts, gdm appears
Not sure if this is a vnc or a gdm bug...

The symptom(s) you're describing seem to indicate that you haven't enabled XDMCP
in your LOGINMANAGER (gdm). By default, XDMCP is disabled, but is required for
vnc-ltsp-config to work. Please confirm.
In gdmsetup I have enabled remote login .. so I think xdmcp is enabled.
xdmcp is indeed enabled (checked in /etc/gdm/custom.conf).
However, what I found just now was that doing init 3 && init 5 to restart GDM
fixed the problem. Not really sure what is going on, but I am confident this is
not a bug in vncts-ltsp-config, so closing. Sorry for the noise.
