LOGIND.CONF(5) logind.conf LOGIND.CONF(5)
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 are previously unused, "autovt" services are
automatically spawned on. These services are instantiated from the template unit
autovt@.service for the respective VT TTY name, for example, autovt AT tty4.service. By
default, autovt@.service is linked to getty@.service. In other words, 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 the 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. Identifies 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 of how many VTs are
allocated by other subsystems, one login "getty" is always available. Defaults to 6
(in other words, there will 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 the user completely logs out (i.e. after the user's last session ended). Defaults
to "no".
Note that setting KillUserProcesses=1 will break tools like screen(1).
KillOnlyUsers=, KillExcludeUsers=
These settings take space-separated lists of usernames 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.
IdleAction=
Configures the action to take when the system is idle. Takes one of "ignore",
"poweroff", "reboot", "halt", "kexec", "suspend", "hibernate", "hybrid-sleep", and
"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 report that they are
idle, no idle inhibitor lock is active, and subsequently, the time configured with
IdleActionSec= (see below) has expired.
IdleActionSec=
Configures the delay after which the action configured in IdleAction= (see above) is
taken after the system is idle.
InhibitDelayMaxSec=
Specifies the maximum time a system shutdown or sleep request is delayed due to an
inhibitor lock of type "delay" being active before the inhibitor is ignored and the
operation executes anyway. Defaults to 5.
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". Note that the lid switch is ignored if the system is inserted in a
docking station, or if more than one display is connected.
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=
default 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.
RuntimeDirectorySize=
Sets the size limit on the $XDG_RUNTIME_DIR runtime directory for each user who logs
in. Takes a size in bytes, optionally suffixed with the usual K, G, M, and T suffixes,
to the base 1024 (IEC). Alternatively, a numerical percentage suffixed by "%" may be
specified, which sets the size limit relative to the amount of physical RAM. Defaults
to 10%. Note that this size is a safety limit only. As each runtime directory is a
tmpfs file system, it will only consume as much memory as is needed.
RemoveIPC=
Controls whether System V and POSIX IPC objects belonging to the user shall be removed
when the user fully logs out. Takes a boolean argument. If enabled, the user may not
consume IPC resources after the last of his sessions terminated. This covers System V
semaphores, shared memory and message queues, as well as POSIX shared memory and
message queues. Note that IPC objects of the root user are excluded from the effect of
this setting. Defaults to "yes".
