Hi Lajos and others.
One of the software support guys here, Joseph H., has found a solution which doesn't require VNC. I am posting his email below. It works for me, I hope it will help others:

*************************

If IDL_IDLBridge requires a X session but does *not* require human
interaction (i.e. clicking buttons in a GUI or monitoring graphical
output) you can do something like this:

1. Create a X frame buffer in a screen session
# screen -dmS FRAMEBUFFER Xvfb -pixdepths 8 16 24 :100

2. Start your IDL process in different screen session
# screen -mS IDL_JOB tcsh -l
[ Inside screen session ]
# setenv DISPLAY :100
# idl
... do stuff
[ Detach screen session ]

The IDL bridge should survive because its "X session" is now using Xvfb
instead of your local X11 forwarding via SSH.

******************

The only difference for me is that I use bash, so I issued

# screen -mS IDL_JOB bash -l
# export DISPLAY=:100

The important thing is that the IDL Bridge has been fooled.

Cheers,
Mario
