Hi,


Below is a piece of copy from my /etc/acpi_handler.sh

...
case "$1" in
button)
case "$2" in
power) /sbin/init 0
/usr/bin/date >> /var/log/battery-log 2>&1
/usr/bin/acpitool -B >> /var/log/battery-log 2>&1
;;

*)
logger "ACPI group $1 / action $2 is not defined"
;;
esac
;;
...

But I never see the /var/log/battery-log exists in my file system and my laptop was running out of battery and got shutdown abnormally.

Is there something wrong in my acpi_handler.sh script?

The command '/sbin/init 0' shuts down your machine. Hence the following lines are not executed.
Try changing the order.

Sorry for the mistake. Now I switched the order of the statements, but still not seen the 'battery-log' file as expected. I really concerns, did the event button/power happen? Or the event group/name is not correct?

You say the script is /etc/acpi_handler.sh. Slackware has the default /etc/acpi/acpi_handler.sh.
Also, where did you get the acpitool command? It is not part of standard Slackware.

Yes, it's actually /etc/acpi/acpi_handler.sh. I build acpitool from source tarball because I don't see what utility in slackware can check the battery usage.

From the command line you have 'cat /sys/class/power_supply/BAT*/uevent'
KDE has a Battery Monitor widget.
XFCE has the Xfce 4 Power Manager system tray icon.
Windowmaker has a number of dockapps for monitoring the battery.
gkrellm can be configured to monitor the battery and will run in any X session.

gkrellm is nice! But it is not able to shutdown my computer when battery is low. I see the 'alert commands', but I think I can not depend on it since my gkrellm must run in normal user mode in X where it does not have privilege to shutdown the system.

So, back to the topic: When acpi power events is not triggering?

What desktop environment or window manager are you running?
Automatic shutdown on low power can be configured in:
KDE using System Settings -> Power Management
XFCE by Settings -> Xfce 4 Power Manager.

I am using fluxbox. And for the moment, I like to stick to this lightweight window manager.

I do not use fluxbox, but the suggestion here http://forums.linuxmint.com/viewtopic.php?f=47&t=42501 is to
Your user will likely need to be a member of the 'power' group.

Hi Allend,

I tried the xfce4-power-manager and found some problems:

1. When run it as non-root user, it's low power action is not configurable and default to do nothing. So how should I start it in fluxbox startup script?
2. 'Hibernate' action does not work. This may not be a fault of xfce4-power-manage. I think I have to enable slackware's hibernate funcationality. But how?

The man page of the program as well as the it's web page don't tell more.

Many thanks & Best Regards,

I have just started a fluxbox session with the line I gave without the & in my ~/.fluxbox/startup
I have no problems with configuring Xfce Power Manager or getting lid switch actions to occur. I have not tested critical battery power events.

Hi, Allend

I am using 0.8.5 xfce4-power-manager on slackware 13.37. Was you using the same version? And, you was running as root or a normal user account?

I did the same configuration to a normal user account. The xfce4-power-manager get runs, but

- The lip actions take no effect. Simply nothing happened if lip closed.
- The On Battery actions are not editable. (right click the xfce4-power-manager icon, and select 'preference', then click 'On Battery').

Yes, tested with 0.8.5 xfce4-power-manager on slackware 13.37 running as a normal user.

I am starting to think that there is a problem with ACPI on your computer. The inability to get the script to run as well as being unable to successfully use xfce4-power-manager would be consistent with this.
Please test your setup, as root, using the information in /usr/doc/pm-utils-1.4.1/README.SLACKWARE and report the findings together with the make and model of your computer.

Thanks for pointing me to the document /usr/doc/pm-utils-1.4.1/README.SLACKWARE. After I added the user account to the 'power' groups, I found the xfce4-power-manage works, I do suspend my computer after 'lip close' or 'batter low'. Thanks a lot!

But I still don't understand why the 'power' action defined in acpi_handler.sh had never triggered. What's the definition of the event? I think making it works is important when I in console mode where the xfc4-power-manage cannot run.

Hope I can continuous to get help, though the current situation is much better after got help from here.

Cheers,
