A free port of the MIT X Windows version 11, release 5 (X11R5) for
80386/80486 UNIX systems
has been developed by a team of programmers headed by David
Wexelblat. The release, known as XFree86, is
available for System V/386, 386BSD, and other i386 UNIX
implementations, including Linux. It includes all of the required
binaries, support files, libraries, and tools.
Configuring and using the X Window System is far beyond the scope of this book. You are encouraged to read The X Window System User's Guide, by Valerie Quercia and Tim O'Reilly. See Appendix A for information on this book. In this section, we'll give a general overview of installing and configuring X Windows for Linux, but it is far from complete. The man pages and README files included with the Linux X Windows distribution should be very helpful.
The Linux XFree86 HOWTO (see Appendix A for details) contains a complete discussion of installation and configuration of X Windows for Linux. We refer all interested readers to this document.
