1.1 root 1: .TH X 1 "10 September 1987" "X Version 11"
2: .SH NAME
3: X - A network transparent window system for Unix
4: .SH DESCRIPTION
5: .PP
6: X is a network transparent windowing system developed at MIT which
7: runs under Ultrix-32 Version 1.2 (and higher), 4.3BSD Unix,
8: SunOS 3.2 (and higher) and
9: DOMAIN/IX. Ports are expected to System V Unix.
10: .PP
11: X display servers run on computers with bitmap terminals.
12: The server
13: distributes user input to, and accepts output requests from various
14: client programs located either on the same machine or elsewhere in the
15: Internet.
16: While
17: a client normally runs on the same machine as the X server it is talking
18: to, this need not be the case.
19: .PP
20: X supports overlapping windows, fully recursive subwindows, text and
21: graphics operations within windows.
22: For a full explanation of functions, see
23: ``Xlib - C Language X Interface'' document and the X Protocol Definition.
24: .PP
25: When you first log in on a display running X, you are
26: using the \fIxterm(1)\fP terminal emulator program.
27: You need not learn anything extra to use a display running X as
28: a terminal beyond moving the mouse cursor into the login window to
29: log in normally.
30: .PP
31: X attempts to provide hooks for your favorite style of user interface;
32: feel free to write your own if you don't like the style provided by
33: existing window managers (see \fIwm(1)\fP or \fIuwm(1)\fP).
34: These programs are used to manipulate existing top level windows,
35: including moving, resizing, and iconifying existing windows.
36: You should start your favorite window manager when you log in
37: on a display running X.
38: .PP
39: Current client programs of X include a terminal emulator (\fIxterm(1)\fP),
40: window managers (\fIwm(1)\fP and \fIuwm(1)\fP),
41: bitmap editor (\fIbitmap(1)\fP),
42: access control program (\fIxhost(1)\fP),
43: user preference setting program (\fIxset(1)\fP),
44: load monitor (\fIxload(1)\fP), clock (\fIxclock(1)\fP),
45: font displayer (\fIxfd(1)\fP) and demos (\fIico(1)\fP, \fImuncher(1)\fP, etc.)
46: On some systems, mail notification has been integrated (\fIbiff(1)\fP).
47: .SH DISPLAY SPECIFICATION
48: .PP
49: When you first log in, the environment variable ``DISPLAY'' will be
50: set to a string ``machine:display'' (for example, ``mit-athena:0'') which
51: will determine which display an X application will talk to by default.
52: .PP
53: Most applications will also interpret an argument with a ``:'' in it
54: to be the display to use.
55: .PP
56: When using DECnet, the format ``node::display'' should be used.
57: .SH "SEE ALSO"
