Hi.
As I understand both tools are able to set the cpu frequency down when idle.
pbvuttonsd.conf even has the option
CPULoad_min = 20 ;percent

But only speedfreq makes /proc/cpuinfo changing the frequency.
Wich one should I user for that? ok, pbbuttons has to manage the spacial keys anyway.
Where can I change the policy?
I set it to dynamic, so ispeedfreq -m shows "New policy: dynamic 400-600 MHz",
but I would like to try 300-600.
What about setting this over the common maximal frequency, such as 620MHz?

Paolo

PBButtonsd does not set the CPU frequency. The setting you've mentioned is a threshold at which pbbuttonsd will not put the system to sleep. This allows you to leave your laptop compiling on battery and have it go to sleep when finished.

There are a number of different CPU freqency switchers available, try them and see which best fits your needs. Each has different uses and performs differently depending upon the number of frequencies available to switch between. The speeds that they choose are built into the processor, it's not advisable to try and change them.

I understand. Sorry for that stupid question.
So speedfreq is doing the switching quite well, between 400 and 600MHz.
If you say both frequencies are "built in", there would be no need for me to look for another tool.
I thought the "speed steps" were changeable.
