I'm using xdmcp regularily which prevents local applications to access 
the screen (becuase only remote access is allowed then). That's why I've 
added localhost to the list of hosts which may always connect.

xauth is used automaticly. You don't have to mess with it unless you do 
some special things.

you're problem is most likely

- your local host has ip xyz.
- the remote host does not know how to connect to xyz since xyz is on 
  another network and only accessible via host pvq.

There is no simple solution to get xdmcp working here. That's why I 
suggested ssh. Installing and starting ssh should be quite simple.
