  <title>Configurar o modo de aplicación única</title>

  <p>Single-application mode is a modified GNOME Shell which configures the
  Shell as an interactive kiosk. The administrator locks down some behavior to
  make the standard desktop more restrictive for users, letting them focus on
  selected features.</p>

  <p>Set up single-application mode for a wide range of functions in a number
  of fields (from communication to entertainment or education), and use it as a
  self-serve machine, event manager, registration point, and so on.</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>usuario</var>]$ mkdir -p ~/.local/bin

[<var>usuario</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>Fai o ficheiro executable:</p>
<code>
[<var>usuario</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>usuario</var>:<var>grupo</var> ~<var>usuario</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>
