    NAME
           systemd-logind.service, systemd-logind - Login manager
    
    SYNOPSIS
           systemd-logind.service
    
           /usr/lib/systemd/systemd-logind
    
    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. 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 [email protected] for each logged
               in user.
    
           ·   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 PolicyKit-based access for users for 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 with logind via the pam_systemd(8) PAM
           module.
