title: X11 connection rejected because of wrong authentication in Mininet
body: <p>I am getting this message whenever I run xterm from within mininet:</p>
  <pre><code>mininet&gt; xterm h1
  mininet&gt; X11 connection rejected because of wrong authentication.
  </code></pre>
  <p>However, if I run it as:</p>
  <pre><code>mininet@mininet-vm:~$ xterm
  </code></pre>
  <p>It shows the window as normal.</p>
  <p>I only experience this issue with Mininet running on virtual box with ubuntu 20.04.02.</p>
  <p>With other ubuntu version (14.04.06), xterm works fine.</p>
  <p>Any help on this would be appreciated..</p>
