LOGIND.CONF(5)logind.confLOGIND.CONF(5)NAMElogind.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.
