Debian and Archlinux use: cpufrequtils

Archlinux

I had to manually configure:

Options:

cpufreq_ondemand (default and recommended)

Dynamically switches between the CPU(s) available clock speeds based on system load

cpufreq_performance

The performance governor runs the CPU(s) at maximum clock speed

cpufreq_conservative

Similar to ondemand, but the CPU(s) clock speed switches gradually through all its available frequencies based on system load

cpufreq_powersave

Runs the CPU(s) at minimum speed

cpufreq_userspace

Manually configured clock speeds by user

Add to rc.conf:

MODULES=(... cpufreq_powersave cpufreq_userspace ...)

I have a new kernel as most archlinux users do and did not need to have the system autoload the modules because they already are.

I use this laptop like a desktop but just in case I created some aliases to switch back and forth:

alias cpu.performance='sudo cpufreq-set -r -g performance'
alias cpu.ondemand='sudo cpufreq-set -r -g ondemand'
 /etc/conf.d/cpufreq
