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 [at] .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.
