6 # This is here to serve as a note to myself, and future developers.
7 #
8 # Any Display manager (gdm,kdm,xdm) has the following problem: if
9 # it is started before any getty, and no vt is specified, it will
10 # usually run on vt2. When the getty on vt2 then starts, and the
11 # DM is already started, the getty will take control of the keyboard,
12 # leaving us with a "dead" keyboard.
13 #
14 # Resolution: add the following line to /etc/inittab
15 #
16 # x:a:once:/etc/X11/startDM.sh
17 #
18 # and have /etc/X11/startDM.sh start the DM in daemon mode if
19 # a lock is present (with the info of what DM should be started),
20 # else just fall through.
21 #
22 # How this basically works, is the "a" runlevel is a additional
23 # runlevel that you can use to fork processes with init, but the
24 # runlevel never gets changed to this runlevel. Along with the "a"
25 # runlevel, the "once" key word means that startDM.sh will only be
26 # run when we specify it to run, thus eliminating respawning
27 # startDM.sh when "xdm" is not added to the default runlevel, as was
28 # done previously.
29 #
30 # This script then just calls "telinit a", and init will run
31 # /etc/X11/startDM.sh after the current runlevel completes (this
32 # script should only be added to the actual runlevel the user is
33 # using).
