Lajos,
thanks for the additional input. With your help, I managed to get the
system up and running. In case anyone is interested, the trick was to
first fire up vncserver to set the password. Then, in the shell script
that is called from the cron job, I first set "vncserver :20" to
create the virtual x window and then also do "setenv DISPLAY
machine_name:20". IDL and the IDL_IDLBridge will then no longer
complain about the missing X connection. Problem solved, although I do
believe that IDL should be more user friendly to this regard.

Thanks very much again for everyone's responses.

Cheers,
Haje
