NAME
systemd-logind.service, systemd-logind - Login manager
SYNOPSIS
systemd-logind.service
/lib/systemd/systemd-logind
DESCRIPTION
systemd-logind is a system service that manages user logins. It is responsible for:
o 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.
o 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.
o Providing PolicyKit-based access for users for operations such as system shutdown or sleep
o Implementing a shutdown/sleep inhibition logic for applications
o Handling of power/sleep hardware keys
o Multi-seat management
o Session switch management
o Device access management for users
o 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[1] for information about the APIs systemd-logind provides.
For more information on the inhibition logic see the Inhibitor Lock Developer Documentation[2].
