How to use Xvfb in Ubuntu 14.04 with/without RandR?
After hours of struggling the error is still there. But finally I've figured out, that it's more like a warning and that Firefox actually starts. Moreover, my Selenium-Tests are running.
The actual problem was, I used an old Selenium Version and the newest Firefox. And they didn't work well together.

I try to run Unit-Tests with Selenium running Firefox on my Ubuntu 14.04 Server. And I'm using Xvfb as described in this blog to simulate a virtual display to show Firefox in.
But Xvfg somehow doesn't load/work with RandR. Because whenever I try this:
sudo Xvfb :10 -ac & export DISPLAY=:10 firefox
I get an
Xlib: extension "RandR" missing on display ":10"
-Error.I've also tried
sudo Xvfb :10 -ac +extension RANDR
,sudo Xvfb :10 -ac -extension RANDR
and beacuse it supplies with "xrandr" alsoapt-get install x11-xserver-utils
.And my setup is a plain empty Ubuntu 14.04 Server with
apt-get install xvfb firefox
.Can anyone please help me run Xvfb with or without RandR?
