Описание (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].
