 Posted: Mon Jul 12, 2004 1:06 pm Post subject: howto display kde logout dialog on power-button-push?!?[SOL] |
 |
|
I want my laptop to display the kde logout dialog when I push the power button.
I know, that I can get that logout-dialog with the console-command:
| Code: | | $ /usr/kde/3.2/bin/dcop kdesktop default logout |
I also can configure the acpid to perform any command, when it receives the acpi-event from the power button. My /etc/acpi/event/default looks like this:
| Code: | ...
# action keeps the command to be executed after an event occurs
# In case of the power event above, your entry may look this way:
#event=button power.*
#action=/sbin/init 0
# Optionally you can specify the placeholder %e. It will pass
# through the whole kernel event message to the program you've
# specified.
event=.*
action=/etc/acpi/default.sh %e
|
It simpley passes the whole argument to /etc/acpi/default.sh in which I can finally define the commands:
| Code: | #!/bin/sh
# Default acpi script that takes an entry for all actions
set $*
group=${1/\/*/}
action=${1/*\//}
case "$group" in
button)
case "$action" in
power) /sbin/init 0
;;
lid) logger "lid switch"
#echo -n "standby" > /sys/power/state
;;
sleep) logger "sleep state"
#echo -n "mem" > /sys/power/state
;;
*) logger "ACPI action $action is not defined"
;;
esac
;;
*)
logger "ACPI group $group / action $action is not defined"
;;
esac |
The problem now is, that this script is obviously run by root. So if I replace /sbin/init 0 with /usr/kde/3.2/bin/dcop kdesktop default logout this doesn't work.
Is there another way, to get the logout dialog? How can I get this working with the shell script, which is executed by the daemon?
greets, christoph

Suid the script.

relevant part of my default.sh (horrible implementation imho)
if anyone has any cleaner way of detecting if the user clicked logout or not it's apriciated 
| Code: |
button)
case "$action" in
power)
if pidof X &>/dev/null; then
if su neuron -c "DISPLAY=:0.0 /usr/kde/3.2/bin/dcop kdesktop" &>/dev/null; then
su neuron -c "DISPLAY=:0.0 /usr/kde/3.2/bin/dcop kdesktop KDesktopIface logout"
for a in 1 2 3 4 5 6 7 8 9 10
do
sleep 2
if pidof gdmgreeter &>/dev/null; then
sleep 5
#/etc/init.d/xdm stop
chvt 1
sync
halt
exit
fi
done
exit
fi
fi
halt
;;
lid)
if pidof X &>/dev/null; then
su neuron -c "DISPLAY=:0.0 /usr/kde/3.2/bin/dcop kdesktop KScreensaverIface lock"
fi
;;
*) logger "ACPI action $action is not defined"
;;
esac
;;

thanks a lot! your solution, neuron, works really fine for me...
i just don't really get it why you do the loop, to check, whether the user clicked log-out.... |
