[SOLVED] how to have pm-powersave set itself properly after suspend

nierro · 2012-05-16 13:07:34

Hi!
I have built my own pm-powersave script, and then i blacklisted every other script in /usr/lib/pm-utils/power.d/* and put my script in /etc/pm/power.d/, chmod +x it.
I have only one problem left to finally love pm-powersave (and forget about laptop-mode-tools and acpid) : it seems that after suspend/hibernation, pm-powersave cannot recognize my state properly (battery or ac) and obviously my power management script is set wrongly.
I noticed that in /usr/lib/pm-utils/sleep.d/ there is a script called 00powersave that tries to do what i need, but probably it isn't working. (as far as i understood, it simply put itself on ac mode before sleeping and then, while resuming, it calls pm-powersave again).
From my logs, i can see the 00powersave script is always executed, but simply sometimes it doesn't work!
Tried with a "sleep 5 &&" before pm-powersave in 00powersave script, but it doesn't fix.
Hope someone can help, i'll post my pm-suspend.log and pm-powersave.log here.
Thanks

as you can see, in pm-powersave.log it says "false" even if i'm on battery.

EDIT2: no repo testing!
EDIT3 : woops sorry... xfce 4.10
EDIT4: the strangest thing is that if i have my power management set wrongly after suspend, simply a "sudo pm-powersave" in terminal fix it.
So i think upower knows in what state the machine is. I believe the problem is all in pm-utils. Please help me!

Woow it seems i can get it fixed, i'm an hero
I had to create a script called 00powersave in /etc/pm/sleep.d/ that is read in place of /usr/lib/pm-utils/sleep.d/00powersave, with following content:

#!/bin/bash

case $1 in
 suspend|hibernate)
	pm-powersave false ;;
 thaw|resume)
	if cat /sys/class/power_supply/AC0/online | grep 0 > /dev/null 2>&1
	then
    		pm-powersave true
	else
    		pm-powersave false
	fi
;;
esac

Hope this can help someone!
I find it very strange that scripts coming with pm-utils won't work with it, but evidently that script is not right (may be someone can explain me why, because for me it looks good).
I have only a little stupid-probably question: i was used to rely on laptop-mode-tools and acpid (daemons) to set my laptop power management. Now that i'm using pm, how can i have power management set even if i'm on a tty? That is, if pm-utils and upower are not executed by a de, how can i have my power management?
Thanks guys!
