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
