| <varlistentry> |
| <term><varname>NAutoVTs=</varname></term> |
| |
| <listitem><para>Takes a positive |
| integer. How many virtual terminals to |
| allocate by default and when switched |
| to autospawn <literal>autovt</literal> |
| services on (if they are otherwise |
| unused). These services are |
| instantiated from a template of |
| <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, and 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> |

| users logging 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> |

| <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 taken before it is ignored and |
| the operation executed |
| anyway. Defaults to |

| <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 warnig 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> |

| </varlistentry> |

| |
| <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> |
