Problem

/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor contains "powersave" but the file scaling_available_governors in the same folder implies that a performance governor is available. Changing the contents of the first file will not persist reboots. Same applies for all (virtual) cpu cores named cpuX in /sys/devices/system/cpu/.

Solution

  1. Install the package cpufreqd (on Arch Linux via the AUR)

  2. Enable the service to start on boot

sudo systemctl enable cpufreqd OR sudo service cpufreqd enable

  1. Either restart now or start the service manually by replacing "enable" with "start" in the previous command.

  2. Verify if it has worked by looking into the contents of the scaling_governor file. It should now contain "performance".

Revert

If you want to revert all the changes

  1. remove the package cpufreqd

  2. either reboot or manually edit the scaling scaling_governor file for each cpuX folder under the path listed above
