Changing Librem Key language settings
-------------------------------------

The Librem Key currently defaults to German as its on-board GPG language setting.
This means when you plug it in, you might get a desktop prompt in German instead of English.
To change the default language used by the Librem Key for GPG, first enter the GPG card edit menu:

.. code-block:: bash

  gpg --card-edit

Then from the ``gpg/card>`` prompt type ``admin`` to enter admin mode and then ``lang`` to change the language.
For instance to change it from German to English, set it to ``en`` when you see the ``Language preferences:`` prompt:

.. code-block::

  admin
  lang

Then type ``quit`` to exit the menu when you are done:

.. code-block::

  quit

.. _librem_key_autolock:

Automatically lock the desktop when removing the Librem Key
-----------------------------------------------------------

Through the use of a simple script and udev rules, you can have your computer lock the screen when you pull out your Librem Key.
This integration requires the following files:

#. ``/etc/udev/rules.d/85-libremkey.rules``
#. ``/usr/local/bin/gnome-screensaver-lock``

.. literalinclude:: _files/85-libremkey.rules

:download:`85-libremkey.rules <_files/85-libremkey.rules>`

.. literalinclude:: _files/gnome-screensaver-lock
   :language: sh

:download:`gnome-screensaver-lock <_files/gnome-screensaver-lock>`

You will need to trigger udev to reload upon installation so it picks up the new rule.
You can do that this way:

.. code-block:: bash

  systemctl restart udev

.. _librem_key_heads_integration:

Using the Librem Key with Heads
-------------------------------

TODO: This section will be incomplete until we finalize the initial Heads UI.
In the meantime, `this blog post <The_Librem_Key_Makes_Tamper_Detection_Easy_>`_ describes how the Librem Key integrates with Heads.
