       systemd-logind.service, systemd-logind - Login manager





       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. This is
           implemented by allocating a systemd slice unit for each user below user.slice, and a
           scope unit below it for each concurrent session of a user. Also, a per-user service
           manager is started as system service instance of user@.service for each logged in

       •   Generating and managing session IDs. If auditing is available and an audit session ID
           is already set for a session, then this ID is reused as the session ID. Otherwise, an
           independent session counter is used.

       •   Providing polkit[1]-based access for users for operations such as system shutdown or

       •   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 with logind via the pam_systemd(8) PAM module.

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

       See sd-login(3) for information about the basic concepts of logind such as users, sessions
       and seats.

       See the logind D-Bus API Documentation[2] for information about the APIs systemd-logind
