title: Squeak 5.0 on 64-bit Linux ignores -headless and -nodisplay
body: <p>I am trying to run the new Squeak 5.0 on 64-bit Linux with no display driver.
  On an older server I always used -nodisplay or -headless and they worked, however now they are ignored and I get this error message:</p>
  
  <pre><code>squeak: could not find any display driver
  </code></pre>
  
  <p>Further details:</p>
  
  <ul>
  <li>squeak was installed via apt-get</li>
  <li>command line: sudo squeak Squeak5.0-15113.image -headless -nodisplay</li>
  <li>The Linux is a Ubuntu, newly installed by 1&amp;1.</li>
  </ul>
