title: Any way to launch Chrome browser without display in Ubuntu?
body: <p>I'm testing my website's frontend with <a href="http://karma-runner.github.io/0.12/index.html" rel="nofollow">karma</a>, using google-chrome as main testing browser in Ubuntu.</p>
  
  <p>The problem is that <a href="http://karma-runner.github.io/0.12/index.html" rel="nofollow">karma</a> occasionally fails to launch chrome browser with <code>Cannot start Chrome</code> error message.</p>
  
  <p>So when I try to launch google chrome with command line in the situation, Chrome throws an <code>Gtk: cannot open display</code> error message.</p>
  
  <p>Although I bump into this error sometimes even when I use my Ubuntu machine directly, I get this error more frequently when I access my machine with <a href="http://www.chiark.greenend.org.uk/~sgtatham/putty/" rel="nofollow">PuTTY</a> from another window machine at my company. </p>
  
  <p>Maybe I can use <a href="http://phantomjs.org/" rel="nofollow">PhantomJS</a> as alternative testing browser, but I need exactly same testing environment as my production website will go through.</p>
