Zenity pop up on remote desktop

[Brian McKee]

Hi All

I remember having this conversation before (maybe the Debian users
mailing list?) a while ago, but don't remember the outcome.

I want to pop up an informational window on a remote computer.
e.g. zenity --warning --text 'hi mom'
does what I want on the computer I'm sitting at, but if I ssh into a
remote machine and run that command you get 'cant open display' even
if run as the user that currently owns the desktop.  How do I get it
running on that display?
