    <title>Installation of libinput</title>

    <para>
      Install <application>libinput</application> by running the following
      commands:
    </para>

<screen><userinput>./configure --prefix=/usr     \
            --disable-libwacom \
            --with-udev-dir=/lib/udev &amp;&amp;
make</userinput></screen>

    <para>
      Running the testsuite for this package can be dangerous, as
      it creates a number of dummy input devices on the currently
      running system that can lead to crashing a local X server or
      a desktop environment. If you understand the risks and have
      the optional <xref linkend="check"/> and
      <xref linkend="valgrind"/> packages installed, the regression
      tests can be run as the <systemitem
      class="username">root</systemitem> user with
      <userinput>make check</userinput>. Note that depending on
      the system configuration and hardware, some tests may fail.
    </para>

      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>make install</userinput></screen>

    <para>
      If <xref linkend="doxygen"/> and <xref linkend="graphviz"/> were
      present during the build, you can install the generated documentation
      by running the following commands as the <systemitem
      class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>install -v -dm755 /usr/share/doc/libinput-&libinput-version; &amp;&amp;
