  <title>Configura el mode aplicació-única</title>

  <p>El mode aplicació-única és una GNOME Shell amb una configuració de Shell com un quiosc interactiu. L'administrador bloqueja alguns comportaments per tal de fer que l'escriptori estàndard sigui més restrictiu per als usuaris, permetent que se centrin en les funcions seleccionades.</p>

  <p>Configureu el mode d'aplicació-única per a una àmplia gamma de funcions en diversos camps (des de la comunicació fins a l'entreteniment o l'educació) i utilitzeu-lo com a màquina autoservei, gestor d'esdeveniments, punt de registre, etc.</p>

  <note style="tip">
    <p>Your distribution might provide the
    <link href="https://gitlab.gnome.org/GNOME/gnome-kiosk">GNOME Kiosk</link>
    session, which is usually available in the gnome-kiosk package. You can use
    it to configure single-application mode more easily. Otherwise,
    use the following procedure.</p>

      <p>As the user that will open the single-application session,
      create the <file>/home/<var>user</var>/.local/bin/gnome-kiosk</file> file:</p>
<code>
[<var>user</var>]$ mkdir -p ~/.local/bin

[<var>user</var>]$ touch ~/.local/bin/gnome-kiosk
</code>
    </item>
    <item>
      <p>Edit the <file>/home/<var>user</var>/.local/bin/gnome-kiosk</file> file and enter
      the executable name of the application that you want to launch in single-application mode.</p>
      <p>For example, to launch the Firefox browser in single-application mode,
      enter the following content:</p>
<code>
#!/bin/sh

while true; do
    firefox --kiosk https://example.org
done
</code>
      <p>The <code>while true</code> loop ensures that the application restarts
      if it terminates for any reason.</p>
    </item>
    <item>
      <p>Make the file executable:</p>
<code>
[<var>user</var>]$ chmod +x ~/.local/bin/gnome-kiosk
</code>
    </item>
    <item>
      <p>If you created the file or its containing directories as a different
      user than the single-application user, such as root, ensure that the file
      has the correct permissions:</p>
<code>
# chown -R <var>user</var>:<var>group</var> ~<var>user</var>/.local
</code>
    </item>
    <item>
      <p>At the GNOME login screen, select the Kiosk session from the gear
      button menu and log in as the single-application user.</p>
    </item>
