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 MY_XDM=$(echo "${DISPLAYMANAGER}" | tr '[:upper:]' '[:lower:]') if [ ${MY_XDM} == gdm ] || [ ${MY_XDM} == gnome ]; then $rc_group_cleanup = "yes"; fi depend() { need localmount xdm-setup # this should start as early as possible # we can't do 'before *' as that breaks it # (#139824) Start after ypbind and autofs for network authentication # (#145219 #180163) Could use lirc mouse as input device # (#70689 comment #92) Start after consolefont to avoid display corruption # (#291269) Start after quota, since some dm need readable home # (#390609) gdm-3 will fail when dbus is not running # (#366753) starting keymaps after X causes problems after bootmisc consolefont modules netmount after readahead-list ypbind autofs openvpn gpm lircmd after quota keymaps before alsasound # Start before X use consolekit dbus xfs } setup_dm() { local MY_XDM MY_XDM=$(echo "${DISPLAYMANAGER}" | tr '[:upper:]' '[:lower:]') # Load our root path from profile.env # Needed for kdm PATH=${PATH}:$(. /etc/profile.env; echo "${ROOTPATH}") NAME= case "${MY_XDM}" in kdm|kde) EXE=/usr/bin/kdm PIDFILE=/var/run/kdm.pid ;; entrance*) EXE=/usr/sbin/entrance PIDFILE=/var/run/entrance.pid ;; gdm|gnome) EXE=/usr/sbin/gdm PIDFILE=/var/run/gdm/gdm.pid START_STOP_ARGS="--background" ;; wdm) EXE=/usr/bin/wdm PIDFILE= ;; gpe) EXE=/usr/bin/gpe-dm PIDFILE=/var/run/gpe-dm.pid ;; lxdm) EXE=/usr/sbin/lxdm-binary PIDFILE=/var/run/lxdm.pid START_STOP_ARGS="--background" ;; lightdm) EXE=/usr/sbin/lightdm PIDFILE=/var/run/lightdm.pid START_STOP_ARGS="--background" ;; *) # first find out if there is such executable EXE="$(command -v ${MY_XDM} 2>/dev/null)" PIDFILE="/var/run/${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 !
