<title>Description</title>
<para>This file configures various parameters of the systemd login manager, <citerefentry><refentrytitle>systemd-logind.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>All options are configured in the
<literal>[Login]</literal> section:</para>
<variablelist>
<varlistentry>
<term><varname>NAutoVTs=</varname></term>
<listitem><para>Takes a positive
integer. Configures how many virtual
terminals (VTs) to allocate by default
that, when switched to and are
previously unused,
<literal>autovt</literal> services are
automatically spawned on. These
services are instantiated from the
template unit
<filename>autovt@.service</filename>
for the respective VT TTY name,
e.g. <filename>autovt@tty4.service</filename>. By
default,
<filename>autovt@.service</filename>
is linked to
<filename>getty@.service</filename>,
i.e. login prompts are started
dynamically as the user switches to
unused virtual terminals. Hence, this
parameter controls how many login
<literal>gettys</literal> 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 <varname>ReserveVT=</varname> is
always subject to this kind of
activation, even if it is not one of
VTs configured with the
<varname>NAutoVTs=</varname>
directive. Defaults to 6. When set to
0, automatic spawning of
<literal>autovt</literal> services is
disabled.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>ReserveVT=</varname></term>
<listitem><para>Takes a positive
integer. Configures the number of one
virtual terminal that shall
unconditionally be reserved for
<filename>autovt@.service</filename>
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
<literal>getty</literal> is always
available. Defaults to 6 (in other
words, there will always be a
<literal>getty</literal> available on
Alt-F6.). When set to 0, VT
reservation is
disabled.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>KillUserProcesses=</varname></term>
<listitem><para>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
<literal>no</literal>.</para>
<para>Note that setting
<varname>KillUserProcesses=1</varname>
will break tools like
<citerefentry><refentrytitle>screen</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>KillOnlyUsers=</varname></term>
<term><varname>KillExcludeUsers=</varname></term>
<listitem><para>These settings take
space-separated lists of usernames
that influence the effect of
<varname>KillUserProcesses=</varname>. If
not empty, only processes of users
listed in
<varname>KillOnlyUsers=</varname> will
be killed when they log out
entirely. Processes of users listed in
<varname>KillExcludeUsers=</varname>
are excluded from being
killed. <varname>KillExcludeUsers=</varname>
defaults to <literal>root</literal>
and takes precedence over
<varname>KillOnlyUsers=</varname>,
which defaults to the empty list.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>IdleAction=</varname></term>
<listitem><para>Configures the action
to take when the system is idle. Takes
one of <literal>ignore</literal>,
<literal>poweroff</literal>,
<literal>reboot</literal>,
<literal>halt</literal>,
<literal>kexec</literal>,
<literal>suspend</literal>,
<literal>hibernate</literal>,
<literal>hybrid-sleep</literal>,
<literal>lock</literal>. Defaults to
<literal>ignore</literal>.</para>
<para>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 <varname>IdleActionSec=</varname>
(see below) has expired.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>IdleActionSec=</varname></term>
<listitem><para>Configures the delay
after which the action configured in
<varname>IdleAction=</varname> (see
above) is taken after the system is
idle.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>InhibitDelayMaxSec=</varname></term>
<listitem><para>Specifies the maximum
time a system shutdown or sleep
request is delayed due to an inhibitor
lock of type <literal>delay</literal>
being active before the inhibitor is
ignored and the operation executes
anyway. Defaults to
5s.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>HandlePowerKey=</varname></term>
<term><varname>HandleSuspendKey=</varname></term>
<term><varname>HandleHibernateKey=</varname></term>
<term><varname>HandleLidSwitch=</varname></term>
<listitem><para>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
<literal>ignore</literal>,
<literal>poweroff</literal>,
<literal>reboot</literal>,
<literal>halt</literal>,
<literal>kexec</literal>,
<literal>suspend</literal>,
<literal>hibernate</literal>,
<literal>hybrid-sleep</literal> and
<literal>lock</literal>. If
<literal>ignore</literal>, logind will
never handle these keys. If
<literal>lock</literal>, all running
sessions will be screen-locked; otherwise,
the specified action
will be taken in the respective
event. Only input devices with the
<literal>power-switch</literal> udev
tag will be watched for key/lid switch
events. <varname>HandlePowerKey=</varname>
defaults to
<literal>poweroff</literal>.
<varname>HandleSuspendKey=</varname>
and
<varname>HandleLidSwitch=</varname>
default to <literal>suspend</literal>.
<varname>HandleHibernateKey=</varname>
defaults to
<literal>hibernate</literal>.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>PowerKeyIgnoreInhibited=</varname></term>
<term><varname>SuspendKeyIgnoreInhibited=</varname></term>
<term><varname>HibernateKeyIgnoreInhibited=</varname></term>
<term><varname>LidSwitchIgnoreInhibited=</varname></term>
<listitem><para>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
<literal>off</literal>, the inhibitor
locks taken by applications in order
to block the requested operation are
respected. If <literal>on</literal>,
the requested operation is executed in
any
case. <varname>PowerKeyIgnoreInhibited=</varname>,
<varname>SuspendKeyIgnoreInhibited=</varname>
and
<varname>HibernateKeyIgnoreInhibited=</varname>
default to <literal>off</literal>.
<varname>LidSwitchIgnoreInhibited=</varname>
defaults to
<literal>yes</literal>. This means
that the lid switch does not respect
suspend blockers by default, but the
power and sleep keys do.
