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?

@kowalski I am facing similar issue, and none of the solution suggested here works for me, were you able to run chromedriver on remote box ? — Ankit Jain, Jan 24 '14 at 06:16

Try this:

Xvfb :21 -screen 0 1024x768x24 +extension RANDR &

Xvfb --help

+extension name        Enable extension
-extension name        Disable extension

Whats with the + or - used? What's the difference? – CMCDragonkai Oct 31 '13 at 13:17

From the usage: `+extension name Enable extension -extension name Disable extension` – jordanpg Apr 23 '15 at 17:47

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 – alonisser Apr 24 '14 at 09:50
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 – happy_marmoset Dec 13 '14 at 08:47

It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.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