Web GL works well in Firefox(version 11.0) but does not in Google Chrome (ver.17.0.963) (Error in Chrome= your graphics card doesn't support webgl)
Specs- Core i5 650 Intel HD graphics 4GB DDR3 RAM
(but it works well in win7)
Enable "ignore software rendering blacklist" or in version 22+ "Override software rendering"
This works for me.
Try installing mesa-utils it should work. This works on my i3 with intel HD 2000
