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 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. 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 for information about the APIs systemd-logind provides. For more information on the inhibition logic see the Inhibitor Lock Developer Documentation.
