The X Window System is a large and powerful (and somewhat complex) graphics environment for UNIX systems. The original X Window System code was developed at MIT; commercial vendors have since made X the industry standard for UNIX platforms. Virtually every UNIX workstation in the world runs some variant of the X Window system.
A free port of the MIT X Window System version 11, release 6 (X11R6) for
80386/80486/Pentium UNIX systems
has been developed by a team of programmers originally headed by David
Wexelblat (dwex@XFree86.org). The release, known as XFree86, is
available for System V/386, 386BSD, and other x86 UNIX
implementations, including Linux. It includes all of the required
binaries, support files, libraries, and tools.
In this document, we'll give a step-by-step description of how to install and configure XFree86 for Linux, but you will have to fill in some of the details yourself by reading the documentation released with XFree86 itself. (This documentation is discussed below.) However, using and customizing the X Window System is far beyond the scope of this document---for this purpose you should obtain one of the many good books on using the X Window System.
