Most of us with linux desktops rarely shut it down and powertop can help us identify processes that waste energy. though you need a laptop/notebook to make the maximum out of powertop, even desktop users can benefit from it.

But less watts. That gets at me too! :) And, not that this is the place to complain about this, but shouldn’t it be *fewer* watts? fewer watts, or less wattage/power. But less watts.

And to be honest, after submitting that comment I suddenly though a completely persistent change really wouldn't be good. But maybe persistent for the log-on session would be useful. It's just such a shame to load the app, let it tell me what I need to turn off, let it do it, and then minimize it. I mean, it must be taking up a few of my cycles by constantly monitoring my cycles, right? And that's just one small gripe. I guess I could shove it over to a virtual desktop I'm not using. My other gripe is that a minimized window gets in my way! Christer: I see your point.

The options are only valid as long as the application is open as well (see above comments). @Patrick – anytime you want it to apply any power saving options you’ll need to run ‘sudo powertop’.

For example, if it disables your wireless while on battery you don't want that to be a persistent change, meaning wireless is now off long-term. The changes will be valid as long as you have the application open, so I generally run it and then minimize it. Once you quit they revert. You might check out http://www.lesswatts.org/tips/ for tips on manually setting persistent values. Persistent changes to many of the values would not be something that most users want.

I've had Powertop ever since Phoronix covered it a few months ago I guess. But Every time I run it I get the same suggestions. All I have to do is run it, do all it suggests, press q to quit and run it again all in the same terminal session and it offers the same things (which suggests it never did what I asked in the first place). I obviously run it with sudo so it should have privs to do whatever it needs to... How do I know it's done what it's supposed to? And how do I get it to be more persistent? Do I have to leave it running in the background to save power? I agree with Phil. I’ve had Powertop ever since Phoronix covered it a few months ago I guess.

Is there a way to make the PowerTop recommendations persistent? I've added some recommendations to /etc/rc.local, but after rebooting and re-running PowerTop, the same recommendations come up. Any suggestions? I think that it would be great to be able to have an option within PowerTop to make the recommendations persistent after they have been interactively applied. -P So, I’ve played with PowerTop.
