Mint Fluxbox - how to improve energy efficiency?

[daquirm]

I'm using one of may Mint 9 Fluxbox installs in live mode with persistency on may notebook. It lasts running about 3 hours, while with windows vista (which is pretty crappy system by the way) it lasts 4-6 hours, which is really huge difference. I tried to install Granola, but before I managed to test it, it messed my system to the point I had to reinstall it completely.

The question is how to improve Linux Mint to be more energy efficient? It is very light but it gives me worse battery time than windows with default energy saving profile. Any suggestions?

jump into /etc/laptop-mode

edit laptop-mode.conf
look also to files under conf.d

Thank you, but there's no such file in Fluxbox edition....

[willie42]

open a terminal

Code: Select all

gksu /etc/laptop-mode.conf

see what that does

Zdravim do Holadnska ?

In Mint 9 Fluxbox there's package called pm-utils-powersave-policy it's supposed to be a lighter version of laptop-mode-tools. But which of these two has better results is hard to say though...you have to uninstall one package in order to get the other. This is what I don't wanna do till someone can clearly explain me, why the one is better than the other.

"It's possible to replicate the behaviour of laptop-mode-tools by writing scripts to /usr/lib/pm-utils/power.d/. Of course, that requires more knowledge than editing a few values in /etc/laptop-mode/laptop-modoe.conf"

OK I'm lacking those skills to do anything with these scripts But I found this project, which is aiming towards what I want to have implemented in linux based desktop OS: http://dynamicpower.sourceforge.net/ With the still growing notebook market, this should be priority for the developers...

This is what I'm talking about...Thank you
I tried this example for tweaking the CPU.

Code: Select all

echo 1 > /sys/devices/system/cpu/sched_mc_power_savings

Despite I'm running Mint from live USB with persistent mode, it wasn't saved...
