NAME

       systemd-logind.conf - Login manager configuration file

SYNOPSIS

       systemd-logind.conf

DESCRIPTION

       This files configures various parameters of the systemd login manager.

OPTIONS

       All options are configured in the [Login] section:

       NAutoVTs=
           Takes a positive integer. How many virtual terminals to allocate by default and when switched to autospawn autovt services on (if they
           are otherwise unused). These services are instantiated from a template of autovt@.service with the virtual terminal TTY name, e.g.
           autovt@tty4.service. By default autovt@.service is linked to getty@.service, i.e. login prompts are started dynamically as the user
           switches to unused virtual terminals, and this parameter hence controls how many gettys are available on the virtual terminals.
           Defaults to 6. When set to 0, automatic spawning of autovt services is disabled.

       KillUserProcesses=
           Takes a boolean argument. Configures whether the processes of a user should be killed when she or he completely logs out (i.e. after
           her/his last session ended). Defaults to no.

       KillOnlyUsers=, KillExcludeUsers=
           These settings take space separated lists of user names that influence the effect of KillUserProcesses=. If not empty only processes of
           users listed in KillOnlyUsers will be killed when they log out entirely. Processes of users listed in KillExcludeUsers= are excluded
           from being killed.  KillExcludeUsers= defaults to root and takes precedence over KillOnlyUsers= which defaults to the empty list.

       Controllers=, ResetControllers=
           These settings control the default control group hierarchies users logging are added to. When logging in users will get private control
           groups in all hierarchies listed in Controllers= and be reset to the root control group in all hierarchies listed in ResetControllers=.
           Controllers= defaults to the empty list, ResetControllers= defaults to cpu.

       Note that setting KillUserProcesses=1 will break tools like screen(1).

       Note that KillUserProcesses=1 is a weaker version of kill-session-processes=1 which may be configured per-service for pam_systemd(8). The
       latter kills processes of a session as soon as it ends, the former kills processes as soon as the last session of the user ends.

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:

       o   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.

       o   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.

       o   Providing PolicyKit-based access for users for 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 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 the logind D-Bus API Documentation[1] for information about the APIs systemd-logind provides.

       For more information on the inhibition logic see the Inhibitor Lock Developer Documentation[2].
