description
The
startx script is a front end to xinit(1) that
provides a somewhat nicer user interface for running a
single session of the X Window System. It is often run with
no arguments.
Arguments
immediately following the startx command are used to
start a client in the same manner as xinit(1). The
special argument ’--’ marks the end of client
arguments and the beginning of server options. It may be
convenient to specify server options with startx to change
on a per-session basis the default color depth, the
server’s notion of the number of dots-per-inch the
display device presents, or take advantage of a different
server layout, as permitted by the Xorg(1) server and
specified in the xorg.conf(5) configuration. Some
examples of specifying server arguments follow; consult the
manual page for your X server to determine which arguments
are legal.

startx -- -dpi

To determine
the client to run, startx first looks for a file
called .xinitrc in the user’s home directory.
If that is not found, it uses the file xinitrc in the
xinit library directory. If command line client
options are given, they override this behavior and revert to
the xinit(1) behavior. To determine the server to
run, startx first looks for a file called
.xserverrc in the user’s home directory. If
that is not found, it uses the file xserverrc in the
xinit library directory. If command line server
options are given, they override this behavior and revert to
the xinit(1) behavior. Users rarely need to provide a
.xserverrc file. See the xinit(1) manual page
for more details on the arguments.
The system-wide
xinitrc and xserverrc files are found in the
/etc/X11/xinit directory.
environment variables
DISPLAY
This variable gets set to the name of the display to which
clients should connect. Note that this gets set, not read.
XAUTHORITY
This variable, if not already defined, gets set to
$(HOME)/.Xauthority. This is to prevent the X server, if
not given the -auth argument, from automatically setting
up insecure host-based authentication for the local host. See the
Xserver(1) and Xsecurity(7) manual pages for more
information on X client/server authentication.
files
$(HOME)/.xinitrc
Client to run. Typically a shell script which runs many programs
in the background.
$(HOME)/.xserverrc
Server to run. The default is X.
/etc/X11/xinit/xinitrc
Client to run if the user has no .xinitrc file.
/etc/X11/xinit/xserverrc
Server to run if the user has no .xserverrc file.
