    <note>

    <para>
      Running the testsuite for this package can cause problems. 
      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>ninja test</userinput>. Note that depending on
      the system configuration and hardware, some tests may fail.
