[K12OSN] xdmcp on ltsp5 (SOLVED) ( kind of )

[Steve]

I got xdmcp to work.
It really had nothing to do with video drivers, chipsets,
ltsp-xorg.conf, etc.

It seems that on cent6, if the host isnt running bind, or able to talk
to another dns server, kdm has an issue performing a name lookup or
reverse lookup and crashes, even if i have valid configs in hosts for
host and TC.

Oddly, kdm shows, in netstat,  it has an established connection to an
external dns server when host and tc are the only devices connected to a
switch.

I removed the default gateway, power cycled the TC and x came right up.
