The package to install to manage power profiles is `power-profiles-daemon`. It provides the system service and the `powerprofilesctl` command; the required dependencies are installed automatically.
sudo apt install power-profiles-daemon sudo systemctl enable --now power-profiles-daemon To display and change profiles graphically, the interface depends on your desktop environment: GNOME and KDE Plasma include this functionality in their settings or power-management tools. You generally don’t need to install a separate package if those components are already installed. Check the detected profiles with: powerprofilesctl list “Power Saver” and “Balanced” are normally available; “Performance” depends on hardware support. (... gmail...)
