GDM isn't managing the display.  In all my trials, I was running Xvnc
or vncserver manually.

IIUC, they should be connecting to it via XDMCP over the loopback
interface.  When they try, they hang.  If I don't tell it to XDMCP
query localhost, it sits there with a black screen and a X cursor.

I originally reported that I saw a gdmlogin child being started, but
now I believe this was a misinterpretation.

I did an strace on Xvnc, and it appeared to be waiting in a select()
loop.  Based on the tcpdump output, it appears it sent the last XDMCP
message, so maybe it's waiting for a response from gdm but it never
comes?

I've replicated the problem on another computer, Fedora Core 5 instead of FC3.

I couldn't coax any debugging output from either program.
