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 + + +# Start X Font Server before X +depend() { + need localmount + + # 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) Could use lirc mouse as input device + # (#70689 comment #92) Start after consolefont to avoid display corruption + after bootmisc consolefont modules netmount + after readahead-list ypbind autofs openvpn gpm lircd + before alsasound + + # Start before X + use acpid consolekit hald xfs +} + +setup_dm() { + local MY_XDM="$(echo "${DISPLAYMANAGER}" | tr '[:upper:]' '[:lower:]')" + + # Load our root path from profile.env + # Needed for kdm + PATH="${PATH}:$(. /etc/profile.env; echo "${ROOTPATH}")" + + case "${MY_XDM}" in + kdm|kde|kde2|kde3) + EXE="$(which kdm)" + # kdm takes too long to create a pidfile for baselayout-2 + #PIDFILE=/var/run/kdm.pid + PIDFILE= + ;; + kdm-*) + EXE="/usr/kde/${MY_XDM#kdm-}/bin/kdm" + PIDFILE= + ;; + entrance*) + EXE=/usr/sbin/entranced + PIDFILE=/var/lib/entranced.pid + ;; + gdm|gnome) + EXE=/usr/bin/gdm + [ "${RC_UNAME}" != "Linux" ] && NAME=gdm-binary + PIDFILE=/var/run/gdm.pid + ;; + wdm) + EXE=/usr/bin/wdm + PIDFILE= + ;; + *) + EXE= + # Fix #65586, where MY_XDM is empty so EXE=somedir + [ -x "/usr/bin/${MY_XDM}" ] && [ -f "/usr/bin/${MY_XDM}" ] \ + && EXE="/usr/bin/${MY_XDM}" + if [ -z "${EXE}" ] ; then + EXE=/usr/bin/xdm + PIDFILE=/var/run/xdm.pid + fi + ;; + esac + + if !
