SYSTEMD-LOGIND.SERVICE(8) systemd-logind.service SYSTEMD-LOGIND.SERVICE(8)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:
· 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 Multi-Seat on Linux[1] for an introduction into basic concepts of
logind such as users, sessions and seats.
See the logind D-Bus API Documentation[2] for information about the
APIs systemd-logind provides.
For more information on the inhibition logic see the Inhibitor Lock
Developer Documentation[3].
