Overview

Cygwin/X is a port of the X Window System to the Cygwin API layer for the Microsoft Windows family of operating systems. Cygwin provides a UNIX-like API, thereby minimizing the amount of porting required.

Cygwin/X consists of an X server, X libraries, and nearly all of the standard X clients, such as xterm, xhost, xdpyinfo, xclock, xeyes, etc. Many more X programs are also packaged for Cygwin. See also the features and screenshots pages.

Cygwin/X is licensed under a MIT/X11 style license. Cygwin is licensed under a modified GNU General Public License that specifically allows libcygwin.a to be linked to programs that are licensed under an Open Source Definition compliant license without such linking requiring that those Open Source programs be licensed under the GNU General Public License (see the Cygwin licensing page for more information). Source code and binaries for both projects are freely available.

Downloading and Installing

Cygwin/X is installed via Cygwin's Installer, either setup-x86.exe (for the long available 32-bit version of Cygwin), or setup-x86_64.exe (for the new 64-bit version since 2013), and the installation process is documented in the Cygwin/X User's Guide. Whether or not you already have Cygwin installed, you can add Cygwin/X to your installation by downloading the latest setup-x86.exe (32-bit installation) or setup-x86_64.exe (64-bit installation), running setup, and selecting the 'xinit' package from the 'X11' category.

Using Cygwin/X is documented in a step-by-step manner, with lots of pictures and examples, in the Cygwin/X User's Guide. Please notice, however, that Cygwin/X contains many general-purpose programs, libraries, and functions that are part of all X distributions. It is therefore beyond the scope of the Cygwin/X User's Guide to document all of these X Window System components. To find documentation, for example, for setxkbmap one should consult the generic X documentation such as the setxkbmap(1) manual page. You could always, of course, do a Google search for setxkbmap, which finds the manual page mentioned above.
