Issues with opengl / webgl on Ubuntu 16.04 MATE

[LucasBrown]

System info:

• Ubuntu 16.04.2 LTS (Xenial) 64-bit
• Kernel 4.4.0-47-generic x86_64
• MATE 1.12.1
• Intel i7-6700K
• 64 GB RAM
• GeForce GT 730
• NVIDIA binary driver version 375.39

Some time ago (a few weeks to a couple months), Minecraft stopped working. No biggie; it's a distraction anyway. More recently, I opened Google Earth, and it gave me an error message:

Unknown Graphics Card

Google Earth is unable to identify your graphics card. This is most likely because the driver for your graphics card has not been installed. You may continue but the Google Earth is unlikely to work until you upgrade your driver. For detailed driver download and install instructions please see our Google Earth Online Help Center using the link below.

The link was unhelpful; it only talks about fixing errors on Windows and Mac.

Then a few days ago I came across a link to some WebGL Chrome experiments, none of which worked. So I ran "locate -i webgl", and it turns out that there is exactly one file on my computer that has webgl in its filename (/usr/share/javascript/modernizr/feature-detects/webgl-extensions.js). I distinctly recall various WebGL Chrome experiments running perfectly on this very computer quite recently, so something's up with my WebGL and whatever it is happened within the past few months.

I remembered that Minecraft was having issues, so I fired it up again to see what the error message was:

So something's up with my OpenGL as well, and I definitely had this working a few months ago as well.

So my WebGL / OpenGL broke recently, and casual googling isn't turning up anything helpful. Can any of you help me with this?

I would suspect the NVidia driver. Reinstalling it would be a good start.

glxgears is the standard diagnostic, isn't it? Does that work properly?
