[Bug 119063] FOUND!

[aexl]

I found the reason in my case: (see source below)
when there is more than one dcopserver process, powerbtn.sh rudely shuts down all of them. 

this (extra dcopserver) may come from a second kde session, but also (as
in my case) from a "sudo kate powerbtn.sh" (the second dcopserver lives
on!).

i think the named behaviour is wrong. powerbtn.sh should either
- ask the user in the currently active session
- or just hibernate without destroying anything

best aexl
ps: remarkable fact that bugtracking helped trigger the bug in this case ;-)

from /etc/acpi/powerbtn.sh:

    KDESES=`pidof dcopserver | wc -w`
    if [ $KDESES -eq 1 ] ; then
        # single KDE session -> ask user
        /usr/bin/dcop --all-sessions --all-users ksmserver ksmserver logout 1 2 0
        exit 0
    else
        # more than one KDE session - just send shutdown signal to all of them
        /usr/bin/dcop --all-sessions --all-users ksmserver ksmserver logout 0 2 0 && exit 0
    fi
