.. _Xming: Using the Xming X server to display graphical programs ====================================================== 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. Installing Xming ---------------- #. Download the Xming installer from the `Xming website`_. #. 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'. .. figure:: using_the_xming_x_server_to_display_graphical_programs/xming_installation.png Running Xming: -------------- #. To run Xming, select XLaunch from the Start Menu. #. Select 'Multiple Windows'. This will open each application in a separate window. .. figure:: using_the_xming_x_server_to_display_graphical_programs/xming_display_settings.png #. Select 'Start no client' to make XLaunch wait for other programs (such as PuTTY). .. figure:: using_the_xming_x_server_to_display_graphical_programs/xming_session_type.png #. Select 'Clipboard' to share the clipboard. .. figure:: using_the_xming_x_server_to_display_graphical_programs/xming_clipboard.png #. Finally save the configuration. .. figure:: using_the_xming_x_server_to_display_graphical_programs/xming_save.png #. 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 :ref:`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.
