benötigt (in meinem Fall) mindestens kernel-3.10 script für acpid

/etc/acpi/events/sony

event=sony.*
action=/etc/acpi/actions/sony-laptop.sh %e

alle sony-events abfangen und script ausführen

/etc/acpi/actions/sony-laptop.sh

#!/bin/bash
# ACPI action script to switch powerlevel on sony-laptops
# ONLY TESTED ON SVS13A1C5E
#
# rellig@minad.de
#


# check the switch status
if [ $3 == "00000003" ] ; then

        if [ $4 == "00000000" ] ; then

                echo "performance" > /sys/devices/platform/sony-laptop/thermal_control

        elif [ $4 == "00000001" ] ; then

                echo "silent" > /sys/devices/platform/sony-laptop/thermal_control

        fi

# handle different buttons - in this case zoom-in and zoom-out to switch balanced and performance when in speed-mode
# in my case the status reported from the gfx_switch are flipped, so stamina means speed
elif [ $3 == "00000001" ] ; then

        perflvl=$(</sys/devices/platform/sony-laptop/gfx_switch_status)

        if [[ $4 == "00000014" && $perflvl == "stamina" ]] ; then

                echo "balanced" > /sys/devices/platform/sony-laptop/thermal_control

        elif [[ $4 == "00000015" && $perflvl == "stamina" ]] ; then

                echo "performance" > /sys/devices/platform/sony-laptop/thermal_control

        else

                logger "ACPI event unhandled: $*"

        fi

else

        logger "ACPI event unhandled: $*"
