Elive

Mmmh, in a recent version of Elive you have gnome-power-manager gadget in the desktop

If you right click in the cpu-like e17 module you have some power configurations, does they works ?

no, the work like they want to work, not me :)
There are too many options, I'll try to translate from Czech:
Behaving of saving energy: Automatic save energy: yes/no,this is the lowest option, above are: automaticaly lower power consump., automatical, maximal speed, minimal speed
So strange is that it's not easily to understand. Whay twice something automatical? Just need only: autosave, maximal, minimal.. don't understand others..

Next is set speed: 1, 1.3, 1.6ghz which works only sometimes according to set other options which I don't know which ones cause as I wrote, they're too much

Next is Setting the rules of power consumption: and items are the same as in the first - behaving of saving energy,
so it seems to mee like it's some kind of dualicity

As I see it, there should be only:

automatical rule of saving energy and this leeds to setup ing gnome power manager - brightness on battery, and speed on demand, on low battery switch to low speed, on AC full speed..

manual switch - and choose what frequency
and maybe (just probably don't need cause of manual switch) - minimal speed (max save), maximal speed

All the options that are you talking about, are from the e17 module, right ? (no gnome-power-manager or other things)

yes..

well, then this needs to be reported somewhere else, not like a bug but like a feature-request (improvement), at http://trac.enlightenment.org/e , please report your suggestions for the "cpufreq module" on this site, i will close the bug from here

I think it's made because of translation - the dualicity. Because I have these same options in english and in Czech..

this is possible too, but needs to be also reported to they, its not from elive this module :)
