Re: Patch to enable reboot/shutdown from within the session

Some updates after Gadi's suggestions on IRC:

1) At the end of /usr/share/ldm/rc.d/X99-zzz-logout-action:
xprop -root -notype LDM_LOGOUT_ACTION | sed -ne 's/^LDM_LOGOUT_ACTION = "\(.*\)"/\1/p' > /var/run/ldm-logout-action || true
xprop -root -remove LDM_LOGOUT_ACTION

2) And the following code *somewhere*:
case "$(cat /var/run/ldm-logout-action)" in
    REBOOT)
        exec reboot -fp
        ;;
    HALT)
        exec shutdown -fp
        ;;
esac

somewhere =
a) In /usr/lib/ltsp/screen.d/ldm it works fine, but Gadi said we
shouldn't change the ldm script at this point.

or

b) In /usr/share/ldm/rc.d/I00-haltreboot it works, but has a little
flickering (X starts before the reboot/shutdown happens).
I'm OK with that.


Putting the script in rc.d/X* or rc.d/K* or in ldm.c leaves user
processes running, so it's *not* OK there.

So... I00-haltreboot it is. :-)


Thanks,
Alkis
