XINIT(1)							      XINIT(1)

NAME
       xinit - X Window	System initializer

SYNOPSIS
       xinit [ [ client	] options ] [ -- [ server ] [ display ]	options	]

DESCRIPTION
       The  xinit  program  is	used to	start the X Window System server and a
       first client program on systems	that  cannot  start  X	directly  from
       /etc/init  or  in  environments that use	multiple window	systems.  When
       this first client exits,	xinit will kill	the X server and  then	termi-
       nate.

       If  no specific client program is given on the command line, xinit will
       look for	a file in the user's home directory called .xinitrc to run  as
       a  shell	 script	 to start up client programs.  If no such file exists,
       xinit will use the following as a default:

	    xterm  -geometry  +1+1  -n	login  -display	 :0

       If no specific server program is	given on the command line, xinit  will
       look  for  a file in the	user's home directory called .xserverrc	to run
       as a shell script to start up the server.   If  no  such	 file  exists,
       xinit will use the following as a default:

	    X  :0

       Note  that  this	assumes	that there is a	program	named X	in the current
       search path.  However, servers are  usually  named  Xdisplaytype	 where
       displaytype  is	the  type  of graphics display which is	driven by this
       server.	The site administrator should, therefore, make a link  to  the
       appropriate  type  of  server  on the machine, or create	a shell	script
       that runs xinit with the	appropriate server.

       Note, when using	a .xserverrc script be sure to	``exec''  the  real  X
       server.	 Failing  to  do  this can make	the X server slow to start and
       exit.  For example:

	    exec Xdisplaytype

       An important point is that programs which are run by .xinitrc should be
       run  in	the  background	 if  they do not exit right away, so that they
       don't prevent other programs from starting up.  However,	the last long-
       lived  program  started (usually	a window manager or terminal emulator)
       should be left in the foreground	so that	the script won't  exit	(which
       indicates that the user is done and that	xinit should exit).

       An alternate client and/or server may be	specified on the command line.
       The desired client program and its arguments should  be	given  as  the
       first  command line arguments to	xinit.	To specify a particular	server
       command line, append a double dash  (--)	 to  the  xinit	 command  line
       (after  any  client  and	arguments) followed by the desired server com-
       mand.

       Both the	client program name and	the server  program  name  must	 begin
       with  a	slash  (/) or a	period (.).  Otherwise,	they are treated as an
       arguments to be appended	to their respective startup lines.  This makes
       it  possible  to	 add arguments (for example, foreground	and background
       colors) without having to retype	the whole command line.

       If an explicit server name is not given and the first argument  follow-
       ing the double dash (--)	is a colon followed by a digit,	xinit will use
       that number as the display number instead of zero.  All remaining argu-
       ments are appended to the server	command	line.

EXAMPLES
       Below  are  several examples of how command line	arguments in xinit are
       used.

       xinit   This will start up a server named X and run the	user's	.xini-
	       trc, if it exists, or else start	an xterm.

       xinit --	/usr/X11R6/bin/Xqdss  :1
	       This  is	 how  one  could start a specific type of server on an
	       alternate display.

       xinit -geometry =80x65+10+10 -fn	8x13 -j	-fg white -bg navy
	       This will start up a server named X, and	will append the	 given
	       arguments  to the default xterm command.	 It will ignore	.xini-
	       trc.

       xinit -e	widgets	-- ./Xsun -l -c
	       This will use the command .Xsun -l -c to	start the  server  and
	       will  append the	arguments -e widgets to	the default xterm com-
	       mand.

       xinit /usr/ucb/rsh fasthost cpupig -display ws:1	--  :1 -a 2 -t 5
	       This will start a server	named X	on display 1  with  the	 argu-
	       ments  -a  2  -t	 5.   It will then start a remote shell	on the
	       machine fasthost	in which  it  will  run	 the  command  cpupig,
	       telling it to display back on the local workstation.

       Below  is a sample .xinitrc that	starts a clock,	several	terminals, and
       leaves the window manager running as the	``last'' application.	Assum-
       ing that	the window manager has been configured properly, the user then
       chooses the ``Exit'' menu item to shut down X.

	       xrdb -load $HOME/.Xresources
	       xsetroot	-solid gray &
	       xclock -g 50x50-0+0 -bw 0 &
	       xload -g	50x50-50+0 -bw 0 &
	       xterm -g	80x24+0+0 &
	       xterm -g	80x24+0-0 &
	       twm

       Sites that want to create a common  startup  environment	 could	simply
       create a	default	.xinitrc that references a site-wide startup file:

	       #!/bin/sh
	       . /usr/local/lib/site.xinitrc

       Another approach	is to write a script that starts xinit with a specific
       shell script.  Such scripts are usually named x11,  xstart,  or	startx
       and  are	 a  convenient	way  to	 provide a simple interface for	novice
       users:

	       #!/bin/sh
	       xinit /usr/local/lib/site.xinitrc -- /usr/X11R6/bin/X bc

ENVIRONMENT VARIABLES
       DISPLAY	      This variable gets set to	the name  of  the  display  to
		      which clients should connect.

       XINITRC	      This  variable  specifies	 an init file containing shell
		      commands to start	up the initial windows.	  By  default,
		      .xinitrc in the home directory will be used.

FILES
       .xinitrc	      default client script

       xterm	      client to	run if .xinitrc	does not exist

       .xserverrc     default server script

       X	      server to	run if .xserverrc does not exist
