Xming is an X11 display server for Microsoft Windows operating systems.
Since May 2007 a small donation must be made in order to access newer releases (for one year). BFH has a commercial site license for 2017 which allows every BFH user to install Xming on any BFH devices.
BFH users download Xming:
Everyone else can download an old version from sourceforge.net.
Xming does not require any configuration, it will automatically be used when Xming is started (see statusbar icon) and PuTTY is used with X11 forwarding enabled.
Documentation can be found on its homepage at straightrunning.com.
