  <para>This section discusses how to configure the
  <command>systemd-vconsole-setup</command> system service which configures
  the virtual console font and console keymap.
 
  The <command>systemd-vconsole-setup</command> service reads <filename>
  /etc/vconsole.conf</filename> for configuration information. Decide which
  keymap and screen font will be used. Various language-specific HOWTO's can
  help. with this (see
  <ulink url="http://www.tldp.org/HOWTO/HOWTO-INDEX/other-lang.html"/>. Examine
  <command>localectl list-keymaps</command> output for a list of valid console
  keymaps. Look in
  <filename class="directory">/usr/share/consolefonts</filename> for valid
  screen fonts.</para>

  <para>The <filename>/etc/vconsole.conf</filename> file should contain lines
  of the form: VARIABLE="value". The following variables are recognized:</para>

  <variablelist>

    <varlistentry>
      <term>KEYMAP_TOGGLE</term>
      <listitem>

  <para>An example for a German keyboard and console is given below:</para>

<screen role="nodump"><userinput>cat &gt; /etc/vconsole.conf &lt;&lt; "EOF"
<literal>KEYMAP=de-latin1
FONT=Lat2-Terminus16</literal>
EOF</userinput></screen>

  <para>You can change KEYMAP value at runtime by using the
  <command>localectl</command> utility:</para>

<screen role="nodump"><userinput>localectl set-keymap MAP</userinput></screen>

  <note><para>Please note that <command>localectl</command> command can
  be used  only on a system booted with Systemd.</para></note>

  <para>You can also use <command>localectl</command> utility with the
  corresponding parameters to change X11 keyboard layout, model, variant
  and options:</para>

<screen role="nodump"><userinput>localectl set-x11-keymap LAYOUT [MODEL] [VARIANT] [OPTIONS]</userinput></screen>

  <para>To list possible values for <command>localectl set-x11-keymap</command>
  parameters, run <command>localectl</command> with parameters listed below:
