Lock screen when hibernate or suspend pc via acpi

[Pali Rohár]

Hello,
Kubuntu 8.04 and develop 8.10alfa5 aren't still lock screen, when I hibernate or suspend pc via acpi (sudo /etc/apci/sleep.sh or sudo /etc/acpi/hibernate.sh).
On http://linux-tipps.blogspot.com/2008/06/locking-your-screen-with-dbus-from.html I found, how to fix.
with dbus-send I can lock screen:
dbus-send --session --dest=org.freedesktop.ScreenSaver --type=method_call --print-reply ScreenSaver  org.freedesktop.ScreenSaver.Lock

On site http://linux-tipps.blogspot.com/2008/06/locking-your-screen-with-dbus-from.html is added this to /etc/acpi/resume.d/90-xscreensaver.sh but better is when lock script starts earlier.

I creat new file /etc/acpi/resume.d/50-kde4-lock.sh:

---

#!/bin/sh
for x in /tmp/.X11-unix/*; do
        displaynum=`echo $x | sed s#/tmp/.X11-unix/X##`
        getXuser;
        if [ x"$XAUTHORITY" != x"" ]; then
                export DISPLAY=":$displaynum"
                su $user -c "dbus-send --session --dest=org.freedesktop.ScreenSaver --type=method_call --print-reply /ScreenSaver org.freedesktop.ScreenSaver.Lock"
        fi
done

---

and this fix this problem.
Can you add this script to new kubuntu 8.10?
