	This sounds right and not right. When you ssh to a host, the ssh 
client will typically set up a phony DISPLAY on the remote machine. If you 
want to ssh to the remote box, then it should be as simple as:

Laptop$ ssh desktop
Desktop$ xterm &

... If, when you ssh to dekstop, ssh issues a message to the tune of 
"disabling remote forwarding", then edit your .ssh/known_hosts file, and 
remove the key for "Desktop". SSH in again (this will pick up a new host 
key for desktop). Once your ssh client sees the proper host key for the 
host which you are connecting to, it will then allow for the above process 
to work (Given you haven't disabled X forwarding in your /etc/ssh_config 
or /etc/sshd_config).


If you want to use the tried and true (and insecure) "xhost" method, then:

Laptop$ xhost +Desktop
Laptop$ telnet Desktop
Desktop$ export DISPLAY="Laptop:0.0"
Desktop$ xterm &


	I've been down the xauth road and do not remember fond memories of 
it. It was a difficult process which was thankfully superceded by ssh. I 
would consider it a very last resort if you cannnot get one of the above 
two methods to work.
