xdvi remote query

[Guest]

In RedHat I could command:
xhost + remote.machine.name.edu
and then connect to that machine using:
ssh remote.machine.name.edu
and while on that remote machine, I could issue the command
export DISPLAY=xxx.yyy.zzz.mno:0
which would be my local IP. Then I could see xdvi output on my monitor as issued by the remote machine.
Using ssh and "ssh -Y" I've been unable to do this. Can someone help me with getting this standard linux protocol working?
Thanks.

Re: xdvi remote query

In case someone stumbles on this query with a problem of his/her own, here's what I did to get past the difference between RedHat and Xubuntu.
1) gdmsetup allowed access to the setup for gdm, which contained lots of options with explanations which, in some cases, I couldn't understand. Be that as it may, I changed remote->configure XDMCP to honor indeirect requests (I think), and in Security I changed some values, but, as usual, I changed lots of things, and then
2) used ssh -X (which may or may not have helped, and VOILA, suddenly I was working. I certainly hopes this helps, at least to point someone in the right direction.
