[SOLVED] ACPI action scripts don't start on boot

Hi mates,
i have this problem, i wrote a little acpi script to take care of power management, that works on plug/unplug of the AC, but it doesn't get executed on boot.

This is the /etc/acpi/events/acadapter

# Pass ac_adapter events
event=ac_adapter.*
action=/etc/acpi/actions/acadapter.sh "%e"

This is the /etc/acpi/actions/acadapter.sh

set $*

case "$2" in

    AC|ACAD|ADP0)

        case "$4" in
            ### AC Adapter Disconnected
            00000000)
                # DO SOMETHING
            ;;

            ### AC Adapter Connected
            00000001)
                # DO SOMETHING
            ;;
        esac
    ;;

    *) logger "ACPI action undefined: $2" ;;
esac

As root i can manually trigger the script with something like

/etc/acpi/actions/acadapter.sh 0 ACAD 0 $([ "$(cat /sys/class/power_supply/ACAD/online)" = "1" ] && echo "00000001" || echo "00000000")

but the problem is that placing that line on /etc/rc.local doesn't work and i can't get the power management running if i start the laptop on battery. Also, i don't know if it's possible to send an ac_adapter event to trigger the script.

Any hints?

Re: [SOLVED] ACPI action scripts don't start on boot

Uhm, i'm thinking of migrating the "DO SOMETHING" part to some pm-powersave hook, so i can check for AC and launch pm-powersave on rc.local...

Maybe install acpid, add it to your /etc/rc.conf and modify the created /etc/acpi/handler.sh?

ACPID is installed and correctly started or i'd never be able to catch the events. I ditched handler.sh and used different scripts to handle the "buttons" and "AC" events, to keep the code more readable (the DO SOMETHING part is large).

Re: [SOLVED] ACPI action scripts don't start on boot

Ok i got all working migrating the power management stuff to pm-utils.

I also deleted all the acpi event catcher scripts and returned to the single /etc/acpi/handler.sh. If it can be of interest to someone, the relevant part of the configuration is the following:

/etc/acpi/handler.sh

...
...

    ### AC adapter connected/disconnected
    ac_adapter)
        case "$2" in
            AC|ACAD|ADP0)
                case "$4" in
                    00000000)
                        logger -t ACPI "AC adapter disconnected: $4"
                        /usr/sbin/pm-powersave true
                    ;;
                    00000001)
                        logger -t ACPI "AC adapter connected: $4"
                        /usr/sbin/pm-powersave false
                    ;;
                esac
            ;;
            *)
                logger -t ACPI "ACPI action undefined: $2"
            ;;
        esac
    ;;

...
...

/etc/rc.local

...

[ "$(cat /sys/class/power_supply/ACAD/online)" = "1" ] && /usr/sbin/pm-powersave false || /usr/sbin/pm-powersave true

...

Then all the additional hooks must reside in /etc/pm/power.d/ (the standard ones are located in /usr/lib/pm-utils/power.d/).

Eventual hooks that involve X need to be replicated in something like .xinitrc, because pm-powersave in rc.local can't access the DISPLAY when X is not running.
