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

Solution 1:

Try this:

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

Xvfb --help

+extension name        Enable extension
-extension name        Disable extension

Solution 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.

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It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.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