The `--disable-gpu` flag is a temporary requirement to work around a few bugs. You won't need this\n+flag in future versions of Chrome. See [https://crbug.com/546953#c152](https://bugs.chromium.org/p/chromium/issues/detail?id=546953#c152) and [https://crbug.com/695212](https://bugs.chromium.org/p/chromium/issues/detail?id=695212) for more information.\n+\n+**So I still need Xvfb?**\n+\n+Nope. Headless Chrome doesn't use a window so a display server like Xvfb is\n+no longer needed. You can happily run your automated tests without it.\n+\n+What is Xvfb? Xvfb is an in-memory display server for Unix-like systems that enables you\n+to run graphical applications (like Chrome) without an attached physical display.\n+Many people use Xvfb to run earlier versions of Chrome to do \"headless\" testing.\n+\n **How do I create a Docker container that runs Headless Chrome?**\n \n Check out [lighthouse-ci](https://github.com/ebidel/lighthouse-ci). It has an\n [example Dockerfile](https://github.com/ebidel/lighthouse-ci/blob/master/builder/Dockerfile)\n that uses Ubuntu as a base image, and installs + runs Lighthouse in an App Engine\n Flexible container.\n \n+**Can I use this with Selenium / WebDriver / ChromeDriver**?\n+\n+Right now, Selenium opens a full instance of Chrome.
