Hi guys,
I just want to set the brightness depending on whether my laptop is connected to AC or not. Therefore I tried the following in handler.sh
#!/bin/sh
# Default acpi script that takes an entry for all actions
# NOTE: This is a 2.6-centric script. If you use 2.4.x, you'll have to
# modify it to not use /sys
minspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq`
maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
setspeed="/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"
set $*
case "$1" in
button/power)
#echo "PowerButton pressed!">/dev/tty5
case "$2" in
PBTN|PWRF) logger "PowerButton pressed: $2" ;;
*) logger "ACPI action undefined: $2" ;;
esac
;;
button/sleep)
case "$2" in
SLPB) echo -n mem >/sys/power/state ;;
*) logger "ACPI action undefined: $2" ;;
esac
;;
ac_adapter)
case "$2" in
AC|ACAD|ADP0|AC0)
case "$4" in
00000080)
echo -n $minspeed >$setspeed
xbacklight -set 0
#/etc/laptop-mode/laptop-mode start
;;
00000000)
echo -n $maxspeed >$setspeed
xbacklight -set 0
#/etc/laptop-mode/laptop-mode stop
;;
esac
;;
*) logger "ACPI action undefined: $2" ;;
esac
;;

case "$2" in
BAT0)
case "$4" in
00000081) #echo "offline" >/dev/tty5
xbacklight -set 0
;;
00000001) #echo "online" >/dev/tty5
xbacklight -set 0

esacYou can see that for testing purposes I added xbacklight on the AC as well as BAT handler. I got the states from acpi_listen.

Anyone?
It would be much easier to help if you'd actually ask a question ;-)
Does the xbacklight work at all? ...from console
Does it work in root context?
Try to disable X access control (xhost +local:)

Hi laloch,
Sorry about that. I tried to set the backlight through xbacklight -set 0 to zero when the Laptop is using battery. Therefore I defined xbacklight -set 0 at every possible position within handler.sh but none of that acpi events works. That's why I posted you the output of acpi_listen.
And yes, xbacklight works properly. So it is just a problem with acpid's handler.sh
Does this make clearer what I want?
Regards

If you replace the xbacklight by
logger "some message", does the message appear in /var/log/messages? If it doesn't, you probably need to add acpid to DAEMONS array in /etc/rc.conf
Offline
The xbacklight clearly needs an X server access...
[laloch@uriel ~]$ su
Password:
[root@uriel laloch]# xbacklight
No protocol specified
Cannot open display ":0"Edit:
Do you have something in /sys/class/backlight directory?

Run xhost +local:
The xbacklight should work then, but I don't see this as "proper" solution. /sys/class/backlight would be better.
