Fedora 21 vs. Ubuntu 14.10 Power Consumption On An ASUS Zenbook

[souenzzo]

@mistvieh:
It`s about live images
AND
default installations...

[drago01]

And nothing with gnome-shell speed or video-vdpau stuff?

If you mean s3tc no and no ... either of the above two uses it.

I know about powertop but is it enough? Maybe M. could make like tutorial/article on how he reduced the power consumption.

http://askubuntu.com/questions/112705/how-do-i-make-powertop-changes-permanent

i am planing for years now to make a script to do it
should be easy, just too lazy

just don't turn on power management for your usb mouse and keyboard
the "Autosuspend for USB device USB OPTICAL MOUSE [6-1]" and such
although the "Autosuspend for USB device OHCI PCI host controller [usb6]" usb controller power management seems to be fine

...

edit: seems that the html output puts the usb things as optional, so just do as it is explained in the link and it shouldn't cause problems

so, as root or sudo:

powertop --html
# makes a powertop.html, in current dir for me
echo "#/bin/sh" > PM_script.sh
grep 'echo ' powertop.html | sed 's/.*\(echo.*\);.*/\1/g' >> PM_script.sh

then cp it somewhere and add to rc.local or whatever you have

bla
grep 'echo ' powertop.html | sed 's/.*\(echo.*\);.*/\1/g' >> PM_script.sh
should be
grep 'echo ' powertop.html | sed -e 's/.*\(echo.*\);.*/\1/g' -e 's/\&gt\;/\>/g' >> PM_script.sh
(for powertop 2.4 at least)

ttttriple post~!


edit: actually it still counts USB devices so just edit them out manually from the resulting script
they are, for example; "echo 'auto' > '/sys/bus/usb/devices/6-1/power/control'"

You should do the script if it doesn't take too much time. This would help many people and you would do something good.

just did it for slackware, as that is what i use
to fit it for another distro one wound need to change where the script goes to be executed at boot

it requires root priviledges

#/bin/sh

echo "This script will create /etc/rc.d/rc.powersave and add it to boot"
echo "It uses powertop's html output to make a script that will turn on powersaving mode for some devices"
echo "Make sure to run it only once per computer, as powertop will output only for devices not currently in powersave mode"

if [[ ! -x /usr/sbin/powertop ]]
then
echo
echo "powertop binary not found"
exit 1
fi

if [[ `powertop --version | grep -c versionv2.4` -eq 0 ]]
then
echo
echo "script is currently only for powertop version 2.4"
echo "installed version is" `powertop --version`
exit 1
fi

cd /tmp
powertop --html

# make a script from the .html that powertop made
echo "#/bin/sh" > /etc/rc.d/rc.powersaving
grep 'echo ' powertop.html | sed -e 's/.*\(echo.*\);.*/\1/g' -e 's/\&gt\;/\>/g' | grep -v "/sys/bus/usb/devices" >> /etc/rc.d/rc.powersaving
chmod +x /etc/rc.d/rc.powersaving

# add the script to rc.local
if [[ $(grep -c rc.powersaving /etc/rc.d/rc.local) -eq 0 ]]
then
cat >> /etc/rc.d/rc.local <<EOL

if [ -x /etc/rc.d/rc.powersaving ]; then
    /etc/rc.d/rc.powersaving
fi

EOL
fi

rm powertop.html

Just keep in mind that powertop2tuned is a tool that does the same thing as your script, but easily installable through the Fedora repositories, and integrated into tuned. tuned is what you use in Fedora instead of tlp, in every other distro you must use tlp, or your script, to achieve best results.
