Power management

Idle behavior runs through swayidle, paired with a couple of systemd sleep settings.

~/.config/swayidle/config:

# 5 min -> dim brightness and lock
timeout 300 'brightnessctl -s set 1%; qs -c noctalia-shell ipc call lockScreen lock' resume 'brightnessctl -r'

# 10 min -> turn off displays
timeout 600 'niri msg action power-off-monitors' resume 'niri msg action power-on-monitors'

# 30 min -> suspend then hibernate
timeout 1800 'systemctl suspend-then-hibernate'

# always lock before sleeping
before-sleep 'qs -c noctalia-shell ipc call lockScreen lock'
lock 'qs -c noctalia-shell ipc call lockScreen lock'

Two more settings outside the swayidle config itself:

/etc/systemd/sleep.conf: AllowSuspendThenHibernate=yes, HibernateDelaySec=2h
/etc/systemd/logind.conf: HandlePowerKey=hibernate, HandlePowerKeyLongPress=suspend-then-hibernate

Suspend-then-hibernate needs a swap file or partition sized for hibernation.
