Hi,

if you are using ACPI, there should be a script named /etc/acpi/default.sh which handles ACPI events, including power button.
I am using this to hibernate-ram when pressing the power switch, so my /etc/acpi/default.sh looks like this:


-------------
#!/bin/sh
# /etc/acpi/default.sh
# Default acpi script that takes an entry for all actions

set $*

group=${1%%/*}
action=${1#*/}
device=$2
id=$3
value=$4

log_unhandled() {
logger "ACPI event unhandled: $*"
}

case "$group" in
button)
case "$action" in
power)
/usr/sbin/hibernate-ram
;;

# if your laptop doesnt turn on/off the display via hardware
# switch and instead just generates an acpi event, you can force
# X to turn off the display via dpms. note you will have to run
# 'xhost +local:0' so root can access the X DISPLAY.
#lid)
# xset dpms force off
# ;;

*) log_unhandled $* ;;
esac
;;

ac_adapter)
case "$value" in
# Add code here to handle when the system is unplugged
# (maybe change cpu scaling to powersave mode). For
# multicore systems, make sure you set powersave mode
# for each core!
#*0)
# cpufreq-set -g powersave
# ;;

# Add code here to handle when the system is plugged in
# (maybe change cpu scaling to performance mode). For
# multicore systems, make sure you set performance mode
# for each core!
#*1)
# cpufreq-set -g performance
# ;;

*) log_unhandled $* ;;
esac
;;

*) log_unhandled $* ;;
esac
