E’ possibile impostare manualmente il governor usando il comando cpufreq-set (da root).
sudo cpufreq-set -c 0 -g ondemand
Per installare cpufreq:
sudo aptitude install cpufrequtils
cpufrequtils includes a daemon which allows users to set the desired scaling, governor and min/max clock speeds for all processor cores at boot-time. Before starting the daemon, edit
/etc/conf.d/cpufreqas root, selecting the desired governor and setting the min/max speed for your CPU(s), for example:
/etc/conf.d/cpufreq
#configuration for cpufreq control
# valid governors:
# ondemand, performance, powersave,
# conservative, userspace
governor="ondemand"
# valid suffixes: Hz, kHz (default), MHz, GHz
min_freq="2GHz"
max_freq="3GHz"
