NAME

       logind.conf - Login manager configuration file

SYNOPSIS

       /etc/systemd/logind.conf

DESCRIPTION

       This file configures various parameters of the systemd login manager systemd-logind.service(8).

OPTIONS

       All options are configured in the [Login] section:

       NAutoVTs=
           Takes a positive integer. Configures how many virtual terminals (VTs) to allocate by default that --
           when switched to and previously unused -- autovt services are automatically spawned on. These
           services are instantiated from the template unit autovt@.service for the respective VT 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. Hence, this parameter controls
           how many login gettys are available on the VTs. If a VT is already used by some other subsystem (for
           example a graphical login) this kind of activation will not be attempted. Note that the VT configured
           in ReserveVT= is always subject to this kind of activation, even if it is not one of VTs configured
           with the NAutoVTs= directive. Defaults to 6. When set to 0, automatic spawning of autovt services is
           disabled.

       ReserveVT=
           Takes a positive integer. Configures the number of one virtual terminal that shall unconditionally be
           reserved for autovt@.service activation (see above). The VT selected with this option will be marked
           busy unconditionally so that no other subsystem will allocate it. This functionality is useful to
           ensure that regardless how many VTs are allocated by other subsystems one login getty is always
           available. Defaults to 6 (with other words: there'll always be a getty available on Alt-F6.). When
           set to 0, VT reservation 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.

       IdleAction=
           Configures the action to take when the system is idle. Takes one of ignore, poweroff, reboot, halt,
           kexec, suspend, hibernate, hybrid-sleep, lock. Defaults to ignore.

           Note that this requires that user sessions correctly report the idle status to the system. The system
           will execute the action after all sessions reported that they are idle, and no idle inhibitor lock is
           active, and subsequently the time configured with IdleActionSec= (see below) has passed.

       IdleActionSec=
           Configures the delay after which the action configured in IdleAction= (see above) is taken after the
           system is idle.

       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 in are added to, in
           addition to the name=systemd named hierarchy. These settings take space separated lists of controller
           names. Pass the empty string to ensure that logind does not touch any hierarchies but systemd's own.
           When logging in user sessions 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 for all
           controllers that are not listed in either Controllers= nor ResetControllers= newly created sessions
           will be part of the control groups of the system service that created the session.

       InhibitDelayMaxSec=
           Specifies the maximum time a system shutdown or sleep request is delayed due to an inhibitor lock of
           type delay being active -- before it is ignored and the operation executed anyway. Defaults to 5s.

       HandlePowerKey=, HandleSuspendKey=, HandleHibernateKey=, HandleLidSwitch=
           Controls whether logind shall handle the system power and sleep keys and the lid switch to trigger
           actions such as system power-off or suspend. Can be one of ignore, poweroff, reboot, halt, kexec,
           suspend, hibernate, hybrid-sleep and lock. If ignore logind will never handle these keys. If lock all
           running sessions will be screen locked. Otherwise the specified action will be taken in the
           respective event. Only input devices with the power-switch udev tag will be watched for key/lid
           switch events.  HandlePowerKey= defaults to poweroff.  HandleSuspendKey= and HandleLidSwitch= default
           to suspend.  HandleHibernateKey= defaults to hibernate.

       PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited=, HibernateKeyIgnoreInhibited=,
       LidSwitchIgnoreInhibited=
           Controls whether actions triggered by the power and sleep keys and the lid switch are subject to
           inhibitor locks. These settings take boolean arguments. If off the inhibitor locks taken by
           applications in order to block the requested operation are respected, if on the requested operation
           is executed in any case.  PowerKeyIgnoreInhibited=, SuspendKeyIgnoreInhibited= and
           HibernateKeyIgnoreInhibited= defaults to off, LidSwitchIgnoreInhibited= defaults to yes. This means
           that the lid switch does not respect suspend blockers by default, but the power and sleep keys do.

       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.
