Remote X

[dplist sympatico ca]

Is there a way to display something on local screen when noone is loged in
yet.

Machine X is RedHat 8, and after boot it goes into gdm of course.

I want to login (via ssh) and start an application on the machine X's that
outputs on machine X's monitor.

It's easy if anybody is logged in on machine X. But it's inconvinient to
login onto that machine (closed cabinet, no keyboard, machine is connected
to an LCD projector) - is there a way to display before anybody is logged
in?

Thanks A LOT!
