Cygwin/X is an implementation of the X Window System that runs under Microsoft Windows. It is part of the Cygwin project, and is installed using Cygwin's standard setup system. As with the rest of Cygwin, Cygwin/X is free software, licensed under the GPL.

Cygwin/X originally used XFree86, but now uses the X.Org Server, owing to concerns over XFree86's new license not being compatible with the GPL.

Recent releases of Cygwin/X added support for "rootless" operation, where the X root window is not displayed, and where X applications appear on the Windows desktop as fully-fledged toplevel applications. Before this feature was introduced, all X windows were confined to a single container window (in a manner similar to MDI subwindows).

Cygwin/X Tips

• To start an SSH session with trusted X11 forwarding enabled, type ssh -Y user@machine.name.com

(in previous versions of Cygwin, this was enabled by default, so -Y wasn't needed)
