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?
This question is related to
google-chrome
xvfb
Try this:
Xvfb :21 -screen 0 1024x768x24 +extension RANDR &
Xvfb --help +extension name Enable extension -extension name Disable extension
It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.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
jeues answer helped me nothing :-( 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.
