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?

Whats with the + or - used? What's the difference? – Charlatanism

From the usage: +extension name Enable extension -extension name Disable extension – Faris

Answer 2

Jeue's answer didn't help me. After hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

After that, everything worked very well, even without any "-extension RANDR" switch.

Wow! great saved me after two days of debugging – Endstopped

Seems not needed on my system, because it is already written in /etc/ld.so.conf.d/x86_64-linux-gnu.conf which is loaded from /etc/ld.so.conf – Silvasilvain

Answer 3

It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.

Changing the version in the pom.xml should fix the problem
