1.1 root 1: .TH X 8C "10 September 1987" "X Version 11"
2: .SH NAME
3: X - X window system server
4: .SH SYNOPSIS
5: .B X
6: <display> [ option ... ] <tty>
7: .SH DESCRIPTION
8: .I X
9: is the window system server.
10: It is normally run automatically by \fIinit(8)\fP,
11: which provides the tty argument.
12: The display argument is the number of the bitmap display to service.
13: The number is typically in the range 0-6, and defines the ports the
14: server will accept connections on and the filename of the device.
15: .PP
16: The program \fIxinit(8)\fP is usually used to start
17: X interactively.
18: .PP
19: The X that gets invoked in either of these ways is actually one
20: of a range of servers configured for the hardware you are running
21: on. Their individual peculiarites are documented in separate
22: manual pages in this section.
23: .PP
24: Connections through the Unix domain, through TCP, and through DECnet are
25: currently possible. The connections actually accepted by a server depend
26: on how it was compiled. Unix domain connections are through \fI/dev/X*\fP,
27: where * is the display number.
28: TCP connections are through ports 6000+N (VAX byte order),
29: where N is the display number. DECnet
30: connections are through object name ``X*'', where * is the display number.
31: .SH OPTIONS
32: The following options can be given on the command line to any X server, usually
33: when it is
34: started by \fIinit(1)\fP using information stored in the file \fI/etc/ttys\fP.
35: (see \fIttys(5)\fP for details):

89: .SH
90: INITIALIZATION
91: .PP
92: \fIX(1)\fP and your first \fIxterm(1)\fP are normally started by the
93: \fIinit(8)\fP program.
94: .sp
95: A typical line in \fI/etc/ttys\fP might be:
96: .sp
97: .nf
98: ttyv0 "/etc/xterm -L =-1+1 :0" xterm on secure window="/etc/Xvs100 0 -c -l"
99: .fi
100: .sp
101: However, if you want the xterm to run on a different machine, you might have:
102: .sp
103: .nf
104: remote "/etc/X 0 -l -c" xterm on secure
105: .fi
106: .sp
107: on the server machine and
108: .sp
109: .nf
110: ttyv0 "/exe/xterm -L =-1+1 orpheus:0" xterm on secure
111: .fi
112: .sp
113: on the client machine.
114: .sp
115: .I X
116: maintains an access control list for accepting connections. The host where
117: the server runs is initially on the list.
118: In addition, hosts listed the file
119: \fI/etc/X*.hosts\fP,
120: where \fI*\fP is the display number, are also initially on the list.
121: The format of this file is a list of host names, one per line. DECnet hosts
122: are distinguished from Internet hosts by the existence of a trailing ``::'' in
123: the name.
124: The access control list can be manipulated with \fIxhost(1)\fP.
125: .sp
126: .I X
127: will catch the SIGHUP signal sent by \fIinit(8)\fP
128: after the initial process (usually
129: the login \fIxterm(1)\fP) started on the display terminates.
130: This signal causes all connections to be closed (thereby ``disowning'' the
131: terminal), all resources to be freed, and all defaults restored.
132: .sp
133: The X protocol is documented in ``X.doc''.
134: Note that while X is running, all access to the display must be through
135: the window system.
136: .SH "SEE ALSO"
137: X(1), xinit(1), xterm(1), bitmap(1), xwm(1), xhost(1), xload(1), xset(1), init(8),

139: .SH DIAGNOSTICS
140: Are too numerous to list them all.
141: If run from \fIinit(8)\fP, errors are logged in the file \fI/usr/adm/X*msgs\fP,
142: .SH FILES

151: .SH BUGS
152: The option syntax is inconsistent with itself and \fIxset(1)\fP.
153: .sp
154: If
155: .I X
156: dies before its clients, new clients won't be able to connect until all
157: existing connections have their TCP TIME_WAIT timers expire.
