Help with Power Management

Message

iopi · Post by **iopi** » Sun Dec 04, 2011 10:19 am

Hi -- I'm pretty unfamiliar with power management; I had KDE on my laptop and powerdevil seemed to work well, but I've recently switched to a simplistic openbox desktop.

I followed http://www.gentoo.org/doc/en/power-management-guide.xml and have acpid and laptop-mode-tools emerged.

My ultimate goal right now is to lock my screen on laptop lid close and maybe sleep/hibernate. I edited my acpid default.sh to have a button event for lid. Right now I just want to test that this event is even happening but I get nothing.

lm_lid.sh

Code: Select all

#!/bin/bash


echo "test" > /home/iopi/powereeee
test -x /usr/sbin/laptop_mode || exit 0

# lid button pressed/released event handler
/usr/sbin/laptop_mode auto

I've done a tail on state and it stays at open

Code: Select all

tailf /proc/acpi/button/lid/LID0/state    
state:      open

In general, my laptop is almost always plugged in to power.

Guidance would be much appreciated

. I'm not even sure if acpid is the way to go. I gave a shot at running powerdevil in the background (kded4 and then calling powerdevil module) -- works mostly; the lock screen command doesn't work and some of the other kde calls. I'm wondering if maybe powerdevil has a script for each of the action items?

Thanks!

You say you "get nothing." Does this mean that the shown lm_lid.sh is not executed at all? Please post the full text of your acpid configuration files. Also, install net-misc/socat, run socat - unix:/var/run/acpid.socket, close and reopen the lid, then post the output from that command. This will show us the string that acpid matched against your configuration files.

I'm pretty sure lm_lid.sh is not being executed at all since I do not have the file in my /home/iopi

I tried the command you gave me and closed/opened the lid. But no output. I tried both on root and normal user. Is there a more current route I should be going then acpid? Below are my various configs/outputs/kernel config.

I disable the deprecated ACPI reporting mechanisms and let acpid listen via netlink. It looks like acpid is not receiving the event at all. If it did, you would have received output from the socat run, even if all your other configuration files were wrong.

iopi · Post by **iopi** » Sun Dec 04, 2011 11:56 pm

So disable the reporting mechanism in the kernel and retry? Is there anything I need to do to get netlink set up?

Post by Hu » Mon Dec 05, 2011 2:04 am

You probably already have it set up. The acpid messages will tell you whether it successfully listens to netlink.
