Here is some Python code showing WebDriver with a virtual display provided by Xvfb:

#!/usr/bin/env python

from pyvirtualdisplay import Display

from selenium import webdriver

display = Display(visible=0, size=(800, 600))

display.start()

# now Firefox will run in a virtual display.

# you will not see the browser.

browser = webdriver.Firefox()

browser.get('http://www.google.com')

print browser.title

browser.quit()

display.stop()

install PyVirtualDisplay on Ubuntu/Debian:

$ sudo apt-get install xvfb python-pip

$ sudo pip install pyvirtualdisplay
