[Paraview] How to set up X connection

[chew ping]

Dear Berk

 

well, basically we don't have a very clear idea of how paraview deals with "parallel rendering".
we could "ssh -X" to any of these machines and run "xclock" and the X windows does appear 
at the machine we are from.

on the other hand, while trying to start a "parallel pvserver", everything works fine until when 
a client (paraview) connects to the "parallel pvserver", and we get a window alerting us about 
"parallel rendering disabled"..

by following the thread in paraview mailing list, we got to know that to enable "parallel rendering",
each of the machine running the "parallel pvserver" should be able to generate a "window" to 
do the rendering work. now in order to do that, we are suppose to have xdm ran on startup.

that's where our question is, (because we are not very good at linux) how do we "startup" the xdm?
we do have a login screen in each of the machine.

tried setting the "usr/bin/env DISPLAY=localhost:0" while starting the "parallel pvserver", but still 
the window alert of "parallel rendering disabled" persist. (i guess it's because the "node 0" still can't 
open the window in each process's node.)

any diagnostic test for us to try out?

thanks
