Here are some examples for the conservative governor: # by default it's 444, so we have to change permissions to be able to change values The sysfs values will be configured in /etc/nf. Install sysfsutils: aptitude install sysfsutils Keeping the governor settings between boots # get them from cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors Specify the governor with the GOVERNOR variable: # valid values: userspace conservative powersave ondemand performance ![]() Install the cpufrequtils package: aptitude install cpufrequtilsĮdit /etc/default/cpufrequtils (you might need to create it if it doesn't exist). Note: In most cases, this should be enabled automatically during Debian installation. To switch to another policy, use sudo cpupower frequency-set -g powersave ![]() The 'available cpufreq governors' field shows which governors are currently available, and 'current policy' shows which policy is currently in use.
