setting up a xdmcp to ubuntu 11.10 w/lightdm

[Scott Webster Wood]

Does anyone know how to configure cygwin to do xdmcp to the new ubuntu 
11.10? It appears to have swapped out the old gdm for lightdm. I found 
the conf option that supposedly turns it on to listen for xdmcp and see 
an entry in the lightdm log that says xdmcp reception is enabled but 
when I try to connect with the same old command I used to use to connect 
to the gdm connection, it doesn't work. What might I be missing? I can't 
even get a response on port 6000. Does it need a hosts.allow entry or 
something and if so what is the syntax for lightdm? I checked for 
iptables but it showed nothing enabled/disabled - is there some other 
firewall running in the newer ubuntu dists?
