NAME¶
logind.conf - Login manager configuration fileSYNOPSIS¶
/etc/systemd/logind.confDESCRIPTION¶
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.
