[SOLVED] ACPID doesn't work properly

cypherinside · 2012-03-08 11:46:43

Hello, about power saving, I tried laptop-mode-tools. It's wonderful but the shutdown failed with battery (I tried to disable any option of laptop-mode-tools but I couldn't power off with battery). Actually I'm using cpufrequtils and acpi (I use gnome, so I don't need to setting pm-utils), but I have some questions.
I set /etc/acpi/handler.sh in this way

#!/bin/sh
# Default acpi script that takes an entry for all actions

minspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq`
maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`

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
            SBTN)   echo -n mem >/sys/power/state ;;
            *)      logger "ACPI action undefined: $2" ;;
        esac
        ;;
    ac_adapter)
        case "$2" in
            AC*|AD*)
                case "$4" in
                    00000000)
                        # Brightness
                        echo -n 5 > /sys/class/backlight/acpi_video0/brightness

                        # Frequency
                        for i in {0..3}; do
                            echo -n $minspeed > /sys/devices/system/cpu/cpu${i}/cpufreq/scaling_setspeed

                        setterm -blank 1 -powerdown 2
                    ;;
                    00000001)

       	case "$3" in

		#echo "LID closed!">/dev/tty5
		;;
	    open)
		#echo "LID opened!">/dev/tty5
        	;;
	esac
	;;

    *)
        logger "ACPI group/action undefined: $1 / $2"
        ;;
esac

In /etc/rc.conf

MODULES=(acpi-cpufreq cpufreq_conservative fuse vboxdrv)

and

DAEMONS=(@syslog-ng @crond dbus @networkmanager @cupsd @sshd acpid @alsa @zramswap @psd)

The problem are:
1) Brightness is set always to 10 (max)
2) scaling_setspeed is set always to <unsupported>
3) I don't know if hard disk speed down is set properly (how can I check it?)

I don't understand. I can set them manually... Where I'm wrong?

I'm not certain if your handler.sh is the right conf-file to set that diverse settings.
What I do is simply create a lttle script in my /home and set different powersettings there. I let my rc.local point to the script and things are done easily....
I think that your handler.sh just handles acpi-events..hdparm settings are not part of that, are they ?
xbacklight handles brightness the easy way. Just put it in start-up programs of your DE/WM..
Cpufreq is handled in a lot of ways >> again I don't think handler.sh is part of those...

But I want different settings if I'm in battery or AC mode. I read in the wiki (here and here) that I can do this....

lswest · 2012-03-08 17:05:56

I've got settings in my handler.sh as well. However, most of my important settings are covered by pm-powersave, which is executed from /etc/acpi/power.sh (as directed by /etc/acpi/events/battery). I also have the AUR package for asus scripts installed (I've got an asus laptop), which provides some settings.

To answer your original question:

1. I use pm-powersave for managing my brightness (you can add custom scripts to /etc/pm/power.d/), and simply echo values to the file, same as you're doing. Maybe give that a shot?
2. No idea, never had that issue before, sorry.
3. As for the hdparm command, I've never had it work properly for me, and I'm not sure how to check more (than just enabled/disabled, which is done with hdparm -i /dev/sda). However, I imagine you need to specify the hard drive in your command (hdparm -B 254 /dev/sda, for example). Some people recommend adjusting the spindown_time in the /etc/hdparm.conf file. But again, I don't do so (and I have no complaints about battery life).

Never mind. I reinstalled laptop-mode-tools and before turning off the laptop I stopped it (it's very simple... I don't know why I thought this only now )

Why do you think laptop-mode-tools has anything to do with handler.sh? I've used LMT quite successfully as a daemon in rc.conf and never fiddled with ACPI. To manipulate LMT, there are .conf files in /etc/laptop-mode/conf.d This sounds more like a acpid issue alone (which I would start sooner at boot). AC/battery switching events are handled by LMT which queries ACPI. Cpufrequtils has it's own directory in /etc, or you can have LMT handle it.

From your first post, it looks like you're not even using LMT. You might as well uninstall it if you're going to be more hands on, writing your own scripts.

I don't think this. I installed LMT but the system hung at power off with the battery, so i removed LMT (infact when i wrote the 1st post LMT wasn't installed). Now i found a way to use LMT, so I don't care anymore handler.sh configuration.
