[mdlug] Ubuntu 11.10 lightdm xdmcp

[Scott Webster Wood]

OK, I made it one step further and found that the original website I 
referred to only gave one of two options that needed to enabled. 
Apparently  you need both of these in lightdm.conf:

[XDMCPServer]
enabled=true

[SeatDefaults]
xserver-allow-tcp=true

However it's still not connecting - I am however at least seeing the 
poort 6000 listeners and getting responses in the lightdm log from the 
cygwin XWin query:

any ideas what is missing?
