To display graphical applications from a Linux computer (such as the VSC clusters) on your Windows desktop, you need to install an X Window server. Here we describe the installation of Xming, one such server and freely available.
- Download the Xming installer from the XMing web site.
- Either install Xming from the Public Domain Releases (free) or from the Website Releases (after a donation) on the website.
- Run the Xming setup program on your Windows desktop. Make sure to select 'XLaunch wizard' and 'Normal PuTTY Link SSH client'.
- To run Xming, select XLaunch from the Start Menu.
- Select 'Multiple Windows'. This will open each application in a separate window.
- Select 'Start no client' to make XLaunch wait for other programs (such as PuTTY).
- Select 'Clipboard' to share the clipboard.
- Finally save the configuration.
- Now Xming is running ... and you can launch a graphical application in your PuTTY terminal. Do not forget to enable X11 forwarding as explained on our PuTTY page.
To test the connection, you can try to start a simple X program on the login nodes, e.g., xterm or xeyes. The latter will open a new window with a pair of eyes. The pupils of these eyes should follow your mouse pointer around. Close the program by typing "ctrl+c": the window should disappear.
If you get the error 'DISPLAY is not set', you did not correctly enable the X-Forwarding.
