Xinitrc
From Gentoo Linux Wiki
The xinitrc script is used as a command line parameter to the xinit windowing system initializer.
[edit] Overview
The xinitrc script performs the following actions:
Configure a set of variables:
userresources=$HOME/.Xresources usermodmap=$HOME/.Xmodmap xinitdir=/etc/X11 sysresources=$xinitdir/Xresources sysmodmap=$xinitdir/Xmodmap
Configure the X resource database with system and user resources, using xrdb
Configure the keyboard map using xmodmap
Run the local users ~/.xinitrc script, if this exists
If the local users ~/.xinitrc script does not exist the /etc/X11/chooser.sh script is invoked, if possible.
If the chooser.sh script does not exist, then the twm windows manager, xclock and xterm are started.
