For a permanent change (requires additional configuration steps), you might need to install and configure cpufrequtils and disable the default ondemand service:

sudo apt install cpufrequtils
echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils
sudo systemctl disable ondemand.service

Reverting Changes To return your system to its default power management settings, you can either select Balanced in the GUI Power Settings or use the command line: bash

sudo powerprofilesctl set balanced

Use code with caution. bash

To revert manual cpufrequtils changes:

sudo apt remove cpufrequtils

Or edit /etc/default/cpufrequtils and change GOVERNOR="ondemand" (or remove the file)
