logind.conf - Login manager configuration file
This file configures various parameters of the systemd login manager,
All options are configured in the "[Login]" section:
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, e.g.
firstname.lastname@example.org. 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.
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
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.
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".
Note that setting KillUserProcesses=1 will break tools like
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.
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 report that they are idle, no idle inhibitor lock is
active, and subsequently, the time configured with IdleActionSec=
(see below) has expired.
Configures the delay after which the action configured in
IdleAction= (see above) is taken after the system is idle.
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 5s.
HandlePowerKey=, HandleSuspendKey=, HandleHibernateKey=,
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".
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.
