Power Management

The [power] section allows you to override the default commands executed when a user interacts with the power menu on the login screen.

By default, mdgreet uses standard systemd (specifically systemctl) commands, which work out-of-the-box on most modern Linux distributions like NixOS, Arch, Fedora, and Ubuntu.

[power]
shutdown = "systemctl poweroff"
reboot = "systemctl reboot"
sleep = "systemctl suspend"
hibernate = "systemctl hibernate"

Non-systemd Distributions

If you are using a distribution that does not use systemd as its init system (such as Void Linux or Artix), you will need to override these commands to match your system’s power management utilities (e.g., loginctl, zzz, or direct shutdown commands).

For example, on a system using elogind:

[power]
shutdown = "loginctl poweroff"
reboot = "loginctl reboot"
sleep = "loginctl suspend"
hibernate = "loginctl hibernate"

Note

Ensure that the greeter user has the necessary permissions to execute these commands without a password prompt.
