Description

systemd-logind is a system service that manages user logins. It is responsible for:

  • Keeping track of users and sessions, their processes and their idle state

  • Providing PolicyKit-based access for users to operations such as system shutdown or sleep

  • Implementing a shutdown/sleep inhibition logic for applications

  • Handling of power/sleep hardware keys

  • Multi-seat management

  • Session switch management

  • Device access management for users

  • Automatic spawning of text logins (gettys) on virtual console activation and user runtime directory management

User sessions are registered in logind via the pam_systemd(8) PAM module.

See logind.conf(5) for information about the configuration of this service.

See Multi-Seat on Linux for an introduction into basic concepts of logind such as users, sessions and seats.

See the logind D-Bus API Documentation for information about the APIs systemd-logind provides.

For more information on the inhibition logic see the Inhibitor Lock Developer Documentation.
