On further investigation, it turns out I already had a service called "vnc" running on 5950 - obviously, I started working on this before and forgot about it :)

So far I do not have it working all the way - I am seeing a black screen with a big X and never get to the XDMCP login screen. However, I did make past where you are, but I also used a couple of different online docs. In my case, when restarting xinetd I see this message in /var/log/messages: Mar 29 15:03:21 cpafisxw xinetd[592]: bind failed (Address already in use (errno = 98)). service = vnc-640x480x8 Which in my case is port 5950... Try restarting/reloading xinetd and see if you have a similar message for 5951. I have tried using lsof to identify what is using that port and found nothing, but each time I restart xinetd I see the same error. If anyone has tips for resolving the "black screen with X" problem, I'm all ears. I did not need to change any GDM settings because the machine in question already supports XDMCP logins from any server.
