- Sleep when idle after 10 minutes to 3 hours, counted from the last mouse, keyboard or gamepad input. It never sleeps while something keeps the screen on (Desktop page) or, if you want, while sound is playing. The screen lock locks first when it's on. Sleep now too.
- Buttons: what the power button, the sleep and hibernate keys and (on laptops) closing the
lid do: shut down, sleep, hibernate, hybrid sleep, sleep then hibernate, lock, restart or
nothing. Saved in
/etc/systemd/logind.conf.d/50-xcontrol.confthrough a small root helper (pkexec), and logind re-reads it right away (it's never restarted). - Power profile: power saver, balanced or performance, when power-profiles-daemon (or tuned-ppd) runs.
