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). +# +# Martin Schlemmer +# aka Azarah +# 04 March 2002 + +depend() { + need localmount xdm-setup + + # this should start as early as possible + # we can't do 'before *' as that breaks it + # (#139824) Start after ypbind and autofs for network authentication + # (#145219 #180163) Could use lirc mouse as input device + # (#70689 comment #92) Start after consolefont to avoid display corruption + # (#291269) Start after quota, since some dm need readable home + # (#390609) gdm-3 will fail when dbus is not running + # (#366753) starting keymaps after X causes problems + after bootmisc consolefont modules netmount + after readahead-list ypbind autofs openvpn gpm lircmd + after quota keymaps + before alsasound + + # Start before X + use consolekit dbus xfs +} + +setup_dm() { + local MY_XDM + + MY_XDM=$(echo "${DISPLAYMANAGER}" | tr '[:upper:]' '[:lower:]') + + # Load our root path from profile.env + # Needed for kdm + PATH=${PATH}:$(. /etc/profile.env; echo "${ROOTPATH}") + + NAME= + case "${MY_XDM}" in + kdm|kde) + EXE=/usr/bin/kdm + PIDFILE=/run/kdm.pid + ;; + entrance*) + EXE=/usr/sbin/entrance + PIDFILE=/run/entrance.pid + ;; + gdm|gnome) + # gdm-3 and above has different paths + if [ -f /usr/sbin/gdm ]; then + EXE=/usr/sbin/gdm + PIDFILE=/run/gdm/gdm.pid + START_STOP_ARGS="--background" + AUTOCLEAN_CGROUP="yes" + else + EXE=/usr/bin/gdm + PIDFILE=/run/gdm.pid + fi + [ "${RC_UNAME}" != "Linux" ] && NAME=gdm-binary + ;; + wdm) + EXE=/usr/bin/wdm + PIDFILE= + ;; + gpe) + EXE=/usr/bin/gpe-dm + PIDFILE=/run/gpe-dm.pid + ;; + lxdm) + EXE=/usr/sbin/lxdm-binary + PIDFILE=/run/lxdm.pid + START_STOP_ARGS="--background" + ;; + lightdm) + EXE=/usr/sbin/lightdm + PIDFILE=/run/lightdm.pid + START_STOP_ARGS="--background" + ;; + *) + # first find out if there is such executable + EXE="$(command -v ${MY_XDM} 2>/dev/null)" + PIDFILE="/run/${MY_XDM}.pid" + + # warn user that he is doing sick things if the exe was not found + if [ -z "${EXE}" ]; then + echo "ERROR: Your XDM value is invalid." + echo " No ${MY_XDM} executable could be found on your system." + fi + ;; + esac + + if !
