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 runleve, as was # done previously. # # This script then just calls "tellinit 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() { use xfs hotplug } setup_dm() { source /etc/profile.env export PATH="/bin:/sbin:/usr/bin:/usr/sbin:${ROOTPATH}" local MY_XDM="$(echo ${DISPLAYMANAGER} | awk '{ print tolower($1) }')" case "${MY_XDM}" in kdm|kde|kde2|kde3) EXE="$(which kdm)" ;; entrance*) EXE="$(which entranced)" ;; gdm|gnome) EXE=/usr/bin/gdm ;; wdm) EXE=/usr/bin/wdm ;; *) EXE= for x in /usr/bin /usr/X11R6/bin do # Fix #65586, where MY_XDM is empty so EXE=somedir [ -x "${x}/${MY_XDM}" -a -f "${x}/${MY_XDM}" ] \ && EXE="${x}/${MY_XDM}" done [ -z "${EXE}" ] && EXE="/usr/X11R6/bin/xdm" ;; esac test ! -x "${EXE}" && EXE=/usr/X11R6/bin/xdm SERVICE="${EXE##*/}" } cmdline_opt() { if [[ "$#" -ne 1 ]]; then return 1 fi for opt in $(</proc/cmdline); do case ${opt} in ${1}) eval ${1}="true" ;; esac done } nox() { # Don't start X if we were passed 'nox' at boot (#83680) cmdline_opt nox if [[ "$?" -ne 0 ]]; then return 1 fi if [[ -n "${nox}" ]]; then return 0 else return 1 fi } start() { setup_dm if nox; then einfo "Skipping ${EXE}, received 'nox'" else ebegin "Setting up ${SERVICE}" #save the prefered DM save_options "service" "${EXE}" #tell init to run /etc/X11/startDM.sh after current #runlevel is finished (should *not* be in the "boot" # runlevel). /sbin/telinit a &>/dev/null eend 0 fi } stop() { local retval=0 local curvt="$(fgconsole)" local myexe="$(get_options "service")" local myservice="${myexe##*/}" ebegin "Stopping ${myservice}" rm -f ${svcdir}/options/xdm/service if [ "$(ps -A | grep -e "${myservice}")" ] then start-stop-daemon --stop --quiet \ --exec ${myexe} &>/dev/null retval=$? fi #switch back to original vt chvt "${curvt}" &>/dev/null eend ${retval} "Error stopping ${myservice}." return ${retval} } # vim:ts=4 |
