I don't know IDL. Can you start any other applications with a display to the vnc-server? Like `xterm -display machine:1`? Once you can do that, try starting the application from the xterm. this xterm has already proper display settings and will propagate them. If needed, exchange calls to `your_app -with -options` with `xterm -display machine:1 -e your_app -with -options`. If the xterm does not work properly, remove all X11 security from the vnc-server with the option -ac: `vncserver -ac` or `Xvnc -ac`. (see `Xvnc --help` for more options). If the xterm works properly and your applicaiton does not, try different variants of the display variable (examples to vncserver :1): localhost:1 localhost:1.0 127.0.0.1:1 127.0.0.1:1.0 <machinename>:1 <machinename>:1.0 <machinename><domainname>:1 <machinename><domainname>:1.0 <ipaddress>:1 <ipaddress>:1.0 If the xterm works properly and your application still does not work as expected, it is most likely a bug in the application that it is hardcoded to display :0.0. I've seen too many of these apps. Then you might be helped with one of the variants to access the console with vnc: http://xf4vnc.sourceforge.net/ or http://www.hexonet.de/software/x0rfbserver/ .
