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 user@.service for each user logged in.
 
•Generating and managing session IDs. If auditing is available and an audit session ID is set for a session already, the session ID is initialized from it. Otherwise, an independent session counter is used.
 
•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 with 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[1] for an introduction into 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 provides.
For more information on the inhibition logic see the Inhibitor Lock Developer Documentation[3].
