# cp powerbtn.sh powerbtn.sh.bak

#!/bin/sh # /etc/acpi/powerbtn.sh # Initiates a shutdown when the power putton has been # pressed. if ps -Af | grep -q '[k]desktop' && test -f /usr/bin/dcop then dcop --all-sessions --all-users ksmserver ksmserver logout 0 2 0 && exit 0 else /sbin/shutdown -h now "Power button pressed" fi
