The XFree86 Project, Inc


What is XFree86?

The XFree86 Project, Inc is the organisation which produces XFree86 , a freely redistributable open-source implementation of the X Window System which runs on UNIX(R) and UNIX-like operating systems such as Linux, all of the BSD variants, Sun Solaris x86, Mac OS X (via Darwin), as well as other platforms like OS/2 and Cygwin.

XFree86, the product, provides a client/server interface between display hardware (the mouse, keyboard, and video displays) and the desktop environment while also providing both the windowing infrastructure and a standardized application interface (API). XFree86 is platform-independent, network-transparent and extensible.

With XFree86 a user cannot only choose the desktop environment they prefer, but because we are an open-source project, users can also modify and update their systems as they see best. As XFree86 has always been an unabashed supporter of freedom of the user desktop, so we encourage users to customise and personalise their desktops with the application of their choice, whether it be KDE, GNOME, Enlightenment, Blackbox, AfterStep,Window Maker, fvwm or twm.

Our goal at XFree86 is to have X run on every platform available, including those we do not currently support, as the best windowing system available on that platform.
