# $Header: /var/cvsroot/gentoo-x86/x11-base/xorg-server/files/xdm.initd-4,v 1.1 2011/11/16 21:49:59 chithanh Exp $
# This is here to serve as a note to myself, and future developers.
#
# Any Display manager (gdm,kdm,xdm) has the following problem: if
# it is started before any getty, and no vt is specified, it will
# usually run on vt2. When the getty on vt2 then starts, and the
# DM is already started, the getty will take control of the keyboard,
# leaving us with a "dead" keyboard.
#
# Resolution: add the following line to /etc/inittab
#
# x:a:once:/etc/X11/startDM.sh
#
# and have /etc/X11/startDM.sh start the DM in daemon mode if
# a lock is present (with the info of what DM should be started),
# else just fall through.
#
# How this basically works, is the "a" runlevel is a additional
# runlevel that you can use to fork processes with init, but the
# runlevel never gets changed to this runlevel. Along with the "a"
# runlevel, the "once" key word means that startDM.sh will only be
# run when we specify it to run, thus eliminating respawning
# startDM.sh when "xdm" is not added to the default runlevel, as was
# done previously.
#
# This script then just calls "telinit a", and init will run
# /etc/X11/startDM.sh after the current runlevel completes (this
# script should only be added to the actual runlevel the user is
# using).
