Comment 14 for bug 1654583

I guess the reason that we can't detect anything is that we'd need something like "OpenGL shading language version string: 1.20", which isn't reported by your graphics driver. 1.20 is our minimum supported version for the shading language.

This is what the output looks for me on a working Intel card on Ubuntu:

$ glxinfo | grep Open
