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 user logged in.
· Generating and managing session IDs. If auditing is available and
an audit session ID is set for a session already, the session ID
is initialized from it. Otherwise, an independent session counter
is used.
· Providing PolicyKit-based access for users to 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].
