I'm running Ubuntu 9.10 Karmic on a laptop and I'm trying to disable the CPU Frequency Scaling.

I've been to several sites and tried a few different things. Nothing seems to really work as errors occur when I TRY these METHODS(The only ones I can find are for dual core processors). This laptop has a single core processor. Can anyone provide some links or advice that might be useful?Hello,

I don't see why you would want to turn off CPU frequency scaling. When you execute an application that requires some CPU, the CPU accelerates to 100%. This wastes power and drains battery if running on laptop.

You may want to do that to test bad drivers.

I agree with TheUnixGuy, especially on a laptop. Unless the scaling is creating instability due to overclocking or something, I'd stick with it. I personally use the "CONSERVATIVE" governor at all times (as "ondemand" has been known to cause stability problems on my cpu).

Anyway, I think in Ubuntu cpufreq is probably compiled into ther kernel, and so complete REMOVAL would require a kernel recompile.

EDIT: btw, the "performance" governor is full speed all the time.My laptop never runs on batteries. It uses AC only, so battery life isn't a concern for me. Thanks for the link Ubermensch, I'll take a thorough look at it tonight when I GET off of work.Hello,
