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 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 polkit[1]-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 *org.freedesktop.login1*(5) and *org.freedesktop.LogControl1*(5) for information about the D-Bus APIs systemd-logind provides.

For more information on the inhibition logic see the Inhibitor Lock Developer Documentation[2].
