 Posted: Tue Oct 09, 2012 4:05 pm Post subject: Control Laptop Sleep |
 |
|
Hi,
I've been using laptop mode and acpi successfully for the past few months, and I've been very happy with it. However, I'd like to tweak its behavior a little bit. Specifically, if the laptop is connected to AC, I would like it to _not_ go to sleep when the lid is closed. Just blank out the screen.
I believe this is controlled by this script: /etc/acpi/actions/lm_lid.sh, which currently contains the following on my system:
| Code: | #!/bin/bash
#- #! /bin/sh
# lid button pressed/released event handler
#laptop mode helps minimized hdd activity
test -x /usr/sbin/laptop_mode && /usr/sbin/laptop_mode auto
#get the -xauth variable so we can access the display
XAUTH="$( ps -C X f | sed -n 's/.*-auth \(.*\)/\1/p' )"
if [[ -z $XAUTH ]]
then
# if XAUTH is blank try another way to get it
XAUTH="$( ps -C xinit f | sed -n 's/.*-auth \(.*\)serverauth.*/\1Xauthority/p' )"
fi
#Find out if the lid is open or closed
if grep -q open /proc/acpi/button/lid/LID/state
then
ACTION="on"
else
ACTION="off"
fi
# turn the display off or back on
XAUTHORITY=$XAUTH /usr/bin/xset -display :0.0 dpms force $ACTION
|
I believe that the last line makes the laptop go to sleep. Is there any way I can tell it to only turn off the screen. Or figure out if I am currently on AC.
Thank you,

The last line only controls the screen, as in turn on/off, based on the values gathered through this script - it doesn't do anything related to putting the machine to sleep.
Look in the other files for clues, things like `pm-suspend` or `echo mem > /sys/power/state` etc are usually used.

I'm not really sure what is suspending when the lid is being closed then.
I have a /usr/sbin/pm-suspend file which is a symlink to /usr/lib64/pm-utils/bin/pm-action.
Is that what's doing it? Is there a way to tell it to not suspend when on AC?
