xinit - X Window System initializer
... ] [--
program is used to start the X Window System server and a firstclient program on systems thatcannot start X directly from /etc/init
or in environmentsthat use multiple window systems. When this first client exits, xinit
will kill the X server and then terminate.
If no specific client program is given on the command line,xinit will look for a file in the user's home directorycalled .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 directorycalled .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:
Note that this assumes that there is a program named X in the currentsearch path. However, servers are usually named Xdisplaytype where displaytype is the type of graphics display which is driven by thisserver. The site administrator should, therefore, make a link to the appropriate type of server on the machine, or create a shell script thatruns 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:
An important point is that programs which are run by .xinitrcshould be run in the background if they do not exit right away, so that they don't prevent other programs fromstarting up.However, the last long-lived program started (usuallya window manager or terminal emulator) should beleft in the foreground so that the script won't exit (whichindicates that the user is done and that xinit should exit).
An alternate client and/or server may be specified on thecommand line. The desired client program and its arguments should be givenas the first command line arguments to xinit. To specify a particularserver command line, append a double dash (--) to the xinit commandline (after any client and arguments) followed by the desired server command.
Both the client program name and the server program name must begin with aslash (/) or a period (.). Otherwise, they are treated as an arguments to beappended 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 following thedouble dash (--) is a colon followed by a digit, xinit will use that number as the display number instead of zero. All remaining arguments are appended to the server command line.
Below are several examples of how command line arguments in xinit
- This will start up a server named X and run the user's .xinitrc,if it exists, or else start an xterm.
- xinit -- /usr/local/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 givenarguments to the default xterm command. It will ignore .xinitrc.
- xinit -e widgets -- ./Xsun -l -c
- This will use the command ./Xsun -l -c to start the server and willappend the arguments -e widgets to the default xterm command.
- 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 arguments-a 2 -t 5. It will then start a remote shell on the machinefasthost in which it will run the command cpupig, telling itto display back on the local workstation.
Below is a sample .xinitrc that starts a clock, several terminals, andleaves the window manager running as the ``last'' application. Assuming thatthe window manager has been configured properly, the userthen chooses the ``Exit'' menu item to shut down X.
xrdb -load $HOME/.Xresourcesxsetroot -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 createa default .xinitrc that references a site-wide startup file:
Another approach is to write a script that starts xinit with a specificshell script. Such scripts are usually named x11, xstart, orstartx and are a convenient way to provide a simple interface fornovice users:
#!/bin/shxinit /usr/local/lib/site.xinitrc -- /usr/bin/X -br
- This variable gets set to the name of the display to which clients shouldconnect.
- This variable specifies an init file containing shell commands to start up theinitial windows. By default, .xinitrc in the home directory will be used.
- default client script
- client to run if .xinitrc does not exist
- default server script
- server to run if .xserverrc does not exist
