Since you have to deal with the DISPLAY variable in the first place, you are logged in remotely to the machine where you are running IDL, right? And the <IP address> you are setting the DISPLAY variable to, that's the IP address of the machine the screen of which you are sitting by?
Then, how did you log in remotely? A long time ago, when people used telnet, you actually had to deal with the DISPLAY variable. Nowadays, when you are more likely to use ssh, you don't do that. You use ssh with the -X flag instead. Of course, your local machine (the one with the screen) still has to have an X server.

No, I think this is just a problem with how your X-Window
system is set up. It has nothing to do with IDL, unfortunately,
except that IDL interacts with the window system.
But, I have almost no experience with Cygwin, so I can't
be of much help, I'm afraid.
Why didn't you download the Windows version?
Cheers,
David

Ummm... You do realize you should do that at the shell prompt and not at the IDL prompt, right?

I'm afraid this is going to be case sensitive. You
may have to locate the CAP LOCKS key! ;-)
