# 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).
