What is the error? Are you running an x server like xming or cygwin? Have you disabled access control?

PuTTY lets you setup X11 tunneling but is NOT itself an X display manager. The system you launched PuTTY from (presumably a PC) has to have something like Hummingbird Exceed ($$$) or Cygwin/X (FOSS) installed so that X windows can be displayed.

Great response. Just an FYI, Hummingbird is defunct. It's now called Open Text.

Thanks - I didn't know that.

Our management asked us to switch to Cygwin/X some time ago to save money. Prior to that I'd used Exceed here and at most of my UNIX/Linux jobs since 1996 and found it to be a really good product.

Funny: The browser shows "OT" for OpenText when minimized. It isn't REALLY off topic though.

Interesting - I don't see your link in your post but on quoting it I see it.

However as noted above the issue doesn't appear to be the DISPLAY variable setting but rather a lack of a X display manager on his PC.
