By default google chrome would keep webgl features disabled if your gpu driver does not support 3d acceleration. However there are options to force enable it. To enable webgl in Google Chrome launch it with the following flags
Here is the command:
$ google-chrome --enable-webgl --ignore-gpu-blacklist
Now test webgl by opening the following urlhttp://get.webgl.org/
It should show a spinning cube if webgl is working correctly.
Open the following url in chrome
It should show the following data
Graphics Feature Status Canvas: Hardware accelerated Compositing: Hardware accelerated 3D CSS: Hardware accelerated CSS Animation: Accelerated WebGL: Hardware accelerated WebGL multisampling: Hardware accelerated Flash 3D: Hardware accelerated Flash Stage3D: Hardware accelerated Texture Sharing: Hardware accelerated undefined: Hardware accelerated
Note that even if webgl appears to be running, it might not be really hardware accelerated. It might still be relying on software based graphics acceleration use open source libraries like mesa.
