title: How to make Xvfb display visible?
body: <p>I am running selenium through Xvfb on display number :99 like this:</p>
  
  <blockquote>
    <p>/usr/bin/Xvfb :99 -ac -screen 0 1024x768x8 &amp; export DISPLAY=":99" &amp;&amp;
    java -jar /usr/lib/selenium/selenium-server-standalone-2.24.1.jar
    -port 4444</p>
  </blockquote>
  
  <p>However display with number other than :0 is not visible by default. How do I make it visible to actually see what selenium is doing in the browser?</p>
