How to enable WebGL if i m using headless chrome on Ubuntu

Question

How to install webgl in headless chrome in Ubuntu 14? I have tried installing libosmesa6, but this did not work. Can someone please help me out because I wanna use webgl on headless chrome for selenium tests. I'm using nightwatch to run tests.

Answer 1

Use this on Chrome for using osmesa

sudo apt-get install libosmesa
sudo ln -s /usr/lib/x86_64-linux-gnu/libOSMesa.so.6 /opt/google/chrome/libosmesa.so
google-chrome --no-first-run --user-data-dir=~/chrome-stuff --use-gl=osmesa

Warning: If your using osmesa, the entire page will be rendered with osmesa thus making it slow. So, if you can run tests that do not need WebGL, then this is preferable. 
You might also want to know that Chrome itself uses osmesa to headless test. But not all versions. Check out the suported versions here: https://cs.chromium.org/chromium/src/third_party/mesa/README.chromium
Or else, for running headless in general, you can use this: https://gist.github.com/addyosmani/5336747
