NAME

       systemd-user-sessions.service, systemd-user-sessions - Permit user logins after boot, prohibit user logins at shutdown

SYNOPSIS

       systemd-user-sessions.service

       /lib/systemd/systemd-user-sessions

DESCRIPTION

       systemd-user-sessions.service is a service that controls user logins through pam_nologin(8). After basic system initialization is complete,
       it removes /run/nologin, thus permitting logins. Before system shutdown, it creates /run/nologin, thus prohibiting further logins.

       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].
