Re: 3x+ battery life

I decided to go for the pm-utils way, but I rebuild upower without idevice support so it doesn't need additional dependencies. If you want to do the same, use this PKGBUILD:

pkgname=upower
pkgver=0.9.16
pkgrel=1
pkgdesc="Abstraction for enumerating power devices, listening to device events and querying history and statistics"
arch=('i686' 'x86_64')
url="http://upower.freedesktop.org"
license=('GPL')
depends=('udev' 'libusb' 'polkit' 'pm-utils' 'dbus-glib')
makedepends=('intltool' 'gobject-introspection' 'docbook-xsl')
options=('!libtool')
source=($url/releases/$pkgname-$pkgver.tar.xz)
sha256sums=('eb9a3d39a8cb62970fd612e333bc7a43437ab0e7890303578b0a7e3c67c8c212')

build() {
  cd "$pkgname-$pkgver"

  # put udev files in /usr/lib
  sed -i "/slashlibdir=/s#/lib#/usr/lib#" configure

  ./configure --prefix=/usr --sysconfdir=/etc \
      --localstatedir=/var \
      --libexecdir=/usr/lib/upower \
      --with-systemdsystemunitdir=/usr/lib/systemd/system \
      --disable-static \
      --without-idevice
  make
}

package() {
  cd "$pkgname-$pkgver"
  make DESTDIR="$pkgdir" install
}

Re: 3x+ battery life

I found easier anyway to use acpid, and put a line in rc.local smile (or creating a systemd unit, as i did) .

Hm, here's a disadvantage of using handler.sh: it will only switch power states when you (un)plug the power. When you boot with power unplugged, it will not automatically trigger powerdown.

That problem can be solved by adding few lines to rc.local for example.

Re: 3x+ battery life

it depends: do you want to use acpid with pm-utils or acpid with powerdown and powerup script?
In the first case you only must put "pm-powersave" in rc.local.
In the second

if cat /sys/class/power_supply/AC0/online | grep 0 > /dev/null 2>&1
then
powerdown
else 
powerup
fi

Re: 3x+ battery life

For those of you looking for the pm-utils way of doing things, you can find my script here:
https://github.com/Unia/Powersave

Thought it might come in handy for some of you. All credit goes to Taylorchu for his initial work on this!

Re: 3x+ battery life

Your script looks great dear Unia, i'm using it, i think it's confortable...I've just a problem with setting brightness...when i'm in 'powersave' mode, it is correctly set to '0', but when i return to 'normal' mode, it's not set back to '9' but remains to '0'
I tried to edit file manually but i got this error:

"/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/backlight/acpi_video0/brightness" E667: Fsync failed

Can anyone help me to solve this issue?

EDIT: I don't know why but now the problem seems to be solved...

Just to be clear; did you notice the README I made? It says you have to edit the variable there, as it differs per manufacturer and even model.

Re: 3x+ battery life

Cool project! I'm trying this script out together with /etc/acpi/handler.sh. By the way, what's the basic difference between

echo -n mem > /sys/power/state 

and

pm-suspend

?

According to the pm-utils Wiki, pm-utils (thus pm-suspend) is a more robust tool than just echoing the state into the kernel (?). In this case, more robust means that it works well with for example proprietary drivers such as Catalyst. For this reason, I am using pm-utils instead of echoing the state.

I have to say though, that I have never used the echoing way of doing it so it might just work perfect for you. Also, I'm not sure if there are any other differences.

Re: 3x+ battery life

I have to say though, that I have never used the echoing way of doing it so it might just work perfect for you. Also, I'm not sure if there are any other differences.

I replaced my pm-suspend line with echo -n 'mem' > /sys/power/state in my handler.sh and it's working great. Also I made a small addition (some may call it bloat) to my /usr/lib/powerdown-utils to make it easier to see who is using its functions in the error messages:

# log as myself
test -n "$1" && me="$1" || me="powerdown-utils"

# turn on kernel options
opt() {
  echo $2 | tee $1 &>/dev/null
  [[ $? != 0 ]] && echo "[${me}] cannot enable option $1"
}
...
# powerdown - powersave script
source /usr/lib/powerdown-utils "powerdown" 
...
# powerdown - powerup
source /usr/lib/powerdown-utils "powerup" 
...

So the output from plugging in and unplugging AC adapter is now logged as:

[powerup] cannot enable option /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
[powerdown] cannot enable option /sys/devices/system/cpu/sched_smt_power_savings

Re: 3x+ battery life

something to check:
1. root privileges
2. acpi-cpufreq is loaded
3. the module is used on your machine

Re: 3x+ battery life

Simply remove those lines wink if a module cannot be unloaded it means that it's not loaded at all, so you don't need those lines...

Re: 3x+ battery life

Would anyone be interested in contributing to sysconf?

https://bbs.archlinux.org/viewtopic.php?id=144507

Also, I am open to merging projects towards a single complete solution for this problem.

From what I found in this thread (a quick skim) that is missing in sysconf would be:

1. pm-utils integration scripts.
2. Screen brightness control.
3. Curses/dialog UI for creating/editing profiles.
4. Check the README for some TODO items.

Cheers,
Fred

Re: 3x+ battery life

I am experimenting with a slightly personalized powerdown script and I enjoy it a lot. Thanks for this.

In the load function in /usr/lib/powerdown-utils there is the following line:

[[ $(lsmod | grep $1) == "" ]] || return

When I run powerup from an interactive shell I always get exit code 1. If I change that line to how it is in the unload function:

[[ $(lsmod | grep $1) == "" ]] && return 

then I get exit code 0 (success).
Please note that in both cases the modules that should be loaded are actually loaded, so I think that it succeeds.
Am I missing something?

Re: 3x+ battery life

@fred
Sorry, I was not sure about your future plan. Could you talk about it?

@patroclo7
these lines just grep lsmod info and see whether it can grep something. If it can, it means the module is loaded, so unload.

Re: 3x+ battery life

@taylorchu: Yes, I understand. My only problem is that as a result of that specific line powerup always exits with an error code (it does not matter if the modules are already loaded or not), although it loads the modules as expected. Not sure if this has something to do with zsh being my default shell.

[[ $(lsmod | grep $1) = "" ]]
can you confirm that this have different result if the module is loaded or not?
