Starting Xming

Click on the desktop icon for Xming. If you successfully start the server, the appropriate icon will appear in the taskbar in the lower right of your computer. For troubleshooting information, please refer to Straightrunning.


Xming may also be started by clicking on the XLaunch icon (in the above discussion, you started the server by clicking on the Xming desktop)

What is the difference between Xming and Xlaunch? XLaunch permits you to change session parameters. Clicking on XLaunch will result in the display of a series of screens, one after another. Each screen controls different settings.

Display settings

The first screen controls aspects of the display. GaussView requires multiple screens (which is the default). But, if you are using some other client software and you wish to alter the layout, screen one is how you change the values.


Please visit Straightrunning for more information about display settings. When you are satisfied with screen/display configurations, click Next.

Session type

The second screen controls whether to start a client. There is no need to start clients but if you are so inclined, this screen is how you do it. Clients may be started on the local machine (your PC) or on the remote machine (argo). An example of a local client is an xterm window which may be used to enter an ssh command to login to argo.) If you select Start a Program and then click Next, and the third screen will appear asking where to start the client and what client to start. Please visit Straightrunning for more information about starting programs with Xming. When you ready to go on to the next screen, click Next.



Additional parameters

The fourth screen additional parameters, the most important of which is Access Control. Do not disable Access Control by putting a check in the box. Leave it blank.


Please see Straightrunning for more information about what to enter in the various additional parameter fields. When you are ready to go on to the next screen, click Next.

Finish configuration

The fifth screen is used to save the configuration changes for reuse in subsequent sessions.


Please see Straightrunning for more information about saving your configuration and how to use the altered configuration in future sessions.

Important: An X server (be it X-Win or, if you elect to use some other product) must be started after you reboot your local machine, power cycle it, or shutdown the X-Win32 program. Without an X-server running, the GaussView screens or those of any argo software program that uses X-Windows will not appear on your monitor.

Additional Information

For more information about Xming, please right click the icon in the taskbar in the lower right corner of your screen and select "About Xming"
