Dave,

If all you are doing is testing one package I would suggest an easier
way would be to establish an ssh connection with the -Y switch which
will connect you to the remote machine and allow you to activate you gui
software and have it be active on your remote machine.  I do this all of
the time

>From inside a konsole or gnome terminal window use:

ssh -Y domain.com

then activate the program at the prompt.

or you can

ssh -Y domain.com evolution

or if you have to go through a gateway

ssh -Y -t user at gateway.com 'ssh -Y user at domain.com evolution'

This tool has ended up being very easy to use.

Hope this helps.
