+# 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).
