Xlib: extension "RANDR" missing on display ":21". - Trying to run headless Google Chrome

Question

I'm trying to run some Webdriver Maven tests on a headless server via xvfb using Chrome (Firefox also didn't work) but I'm getting this error message:

Xlib:  extension "RANDR" missing on display ":21".

What more information should I provide and what could the problem/solution be?
