I'm trying to set up one Linux machine (Slackware 8.1) to run as an Xterminal to a server (or X client) running Redhat 9. Gnome is the default window manager.

I changed gdm.conf on the Redhat server to say:

[Xdmcp]
Enable=True

and everything works. I connect from the Slackbox simply with

X -broadcast

and get my Gnome desktop.

This is great, exactly what I want. Only problem is that I cannot disconnect. I tell Gnome to shutdown and it returns me to the Redhat box's graphical login prompt. I click on the Disconnect menu item and the screen goes blank for 5 seconds, then returns me to the graphical login prompt.

Any suggestions?

I don't know how to answer your question and I don't know how bad you want to use slackware. But www.k12ltsp.org has a redhat terimnal server that works great with very little setup. Just a thought...
