6 X - a portable, network-transparent window system
7
9 The X Window System is a network transparent window system which runs
10 on a wide range of computing and graphics machines. It should be rela‐
11 tively straightforward to build the X.Org Foundation software distribu‐
12 tion on most ANSI C and POSIX compliant systems. Commercial implemen‐
13 tations are also available for a wide range of platforms.
14 The X.Org Foundation requests that the following names be used when
16 referring to this software:
17 X
20 X Window System
21 X Version 11
22 X Window System, Version 11
23 X11
24 X Window System is a trademark of The Open Group.

28 X Window System servers run on computers with bitmap displays. The
29 server distributes user input to and accepts output requests from vari‐
30 ous client programs through a variety of different interprocess commu‐
31 nication channels. Although the most common case is for the client
32 programs to be running on the same machine as the server, clients can
33 be run transparently from other machines (including machines with dif‐
34 ferent architectures and operating systems) as well.
35 X supports overlapping hierarchical subwindows and text and graphics
37 operations, on both monochrome and color displays. For a full explana‐
38 tion of the functions that are available, see the Xlib - C Language X
39 Interface manual, the X Window System Protocol specification, the X
40 Toolkit Intrinsics - C Language Interface manual, and various toolkit
41 documents.
42 The number of programs that use X is quite large. Programs provided in
44 the core X.Org Foundation distribution include: a terminal emulator,
45 xterm; a window manager, twm; a display manager, xdm; a console redi‐
46 rect program, xconsole; a mail interface, xmh; a bitmap editor, bitmap;
47 resource listing/manipulation tools, appres, editres; access control
48 programs, xauth, xhost, and iceauth; user preference setting programs,

50 oclock; a font displayer, xfd; utilities for listing information about
51 fonts, windows, and displays, xlsfonts, xwininfo, xlsclients, xdpyinfo,
52 xlsatoms, and xprop; screen image manipulation utilities, xwd, xwud,
53 and xmag; a performance measurement utility, x11perf; a font compiler,
54 bdftopcf; a font server and related utilities, xfs, fsinfo, fslsfonts,
55 fstobdf; a display server and related utilities, Xserver, rgb, mkfont‐
