Running inside X Virtual Frame Buffer#16

I have to nightmare script inside xvfb. ``` xvfb-run node cnn.js ``` cnn.js has.... ``` var Nightmare = require('../nightmare'); var vo = require('vo'); vo(run)(function(err, result) { if (err) throw err; }); function *run() { var nightmare = Nightmare(); var title = yield nightmare .goto('http://cnn.com') .evaluate(function() { return document.title; }); console.log(title); yield nightmare.end(); } ``` is there a way to write the whole code inside X Virtual Frame Buffer, so that we can execute in normal way `node cnn.js` instead of `xvfb-run node cnn.js`
