SYSTEMD-LOGIND.SERVICE(8) systemd-logind.service SYSTEMD-LOGIND.SERVICE(8)
NAME
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:
o Keeping track of users and sessions, their processes and their idle state
o Providing PolicyKit-based access for users to 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 in 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].
