<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 to allocate by default that
-- when switched to --
<literal>autovt</literal> services are
automatically spawned on. These
services are instantiated from the
template
<filename>autovt@.service</filename>
with the virtual terminal 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. This
parameter hence controls how many
gettys are available on the virtual
terminals. Defaults to 6. When set to
0, automatic spawning of
<literal>autovt</literal> services 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></listitem>
</varlistentry>
<varlistentry>
<term><varname>KillOnlyUsers=</varname></term>
<term><varname>KillExcludeUsers=</varname></term>
<listitem><para>These settings take
space separated lists of user names
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>Controllers=</varname></term>
<term><varname>ResetControllers=</varname></term>
<listitem><para>These settings control
the default control group hierarchies
users logging in are added to. When
logging in users will get private
control groups in all hierarchies
listed in
<varname>Controllers=</varname> and be
reset to the root control group in all
hierarchies listed in
<varname>ResetControllers=</varname>. <varname>Controllers=</varname>
defaults to the empty list,
<varname>ResetControllers=</varname>
defaults to
<literal>cpu</literal>.</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 it is ignored
and the operation executed
anyway. Defaults to
5s.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>HandlePowerKey=</varname></term>
<term><varname>HandleSleepKey=</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 system power-off or
suspend. Can be one of
<literal>off</literal>,
<literal>no-session</literal>,
<literal>tty-session</literal>,
<literal>any-session</literal> and
<literal>always</literal>. If
<literal>off</literal> logind will
never handle these keys. If
<literal>no-session</literal> logind
will handle these keys when no user is
logged in and no inhibitor lock is
taken, and trigger a warning beep
otherwise. If set to
<literal>tty-session</literal> logind
will handle these keys if no inhibitor
lock is taken, and either no user is
logged in or the foreground session is
a text login and the only one
existing. If
<literal>any-session</literal> is set
logind will handle these keys if no
inhibitor lock is taken, and either no
user is logged in or the foreground
session is the only one existing
(regardless whether graphical or
text). If set to
<literal>always</literal> logind will
handle these keys in any case, even if
one or more users are logged in or an
inhibitor lock is taken. Only input
devices with the
<literal>power-switch</literal> udev
tag will be watched for key
events. <varname>HandlePowerKey=</varname>
defaults to
<literal>no-session</literal>.
<varname>HandleSleepKey=</varname>
defaults to
<literal>tty-session</literal>,
<varname>HandleLidSwitch=</varname>
defaults to
<literal>off</literal>.</para></listitem>
</varlistentry>
</variablelist>
<para>Note that setting
<varname>KillUserProcesses=1</varname> will break tools
like
<citerefentry><refentrytitle>screen</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
<para>Note that <varname>KillUserProcesses=1</varname>
is a weaker version of
<varname>kill-session-processes=1</varname> which may
be configured per-service for
<citerefentry><refentrytitle>pam_systemd</refentrytitle><manvolnum>8</manvolnum></citerefentry>. 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.</para>
