Reading AskUbuntu and on the forums, I am trying to find out what to do about a WebGL and Google MapsGL problem (described in a Google forum thread starting at [post #5](https://productforums.google.com/d/msg/maps/myIiZI02rJk/cV5V0WpaEY0J)).

Specifically, Google's MapsGL works perfectly in Windows 7 (on this same machine with dual-boot), but on Ubuntu, the Photo Tour and 45 Degree Satellite View show grey blurry blobs (see [screen-shot](https://maps-a-googleproductforums-com.googlegroups.com/attach/35a05b854eb3360f/Report%20problem%20marker.png?gda=I5VTPkYAAAC558qHzY3SJ05XjYyu3WlGwt2pDcfwhZXz18DdwgHntczJMb89XTCaH6dflcrIsYZx40jamwa1UURqDcgHarKEE-Ea7GxYMt0t6nY0uV5FIQ&view=1&part=4)).

According to [post #10](https://productforums.google.com/d/msg/maps/myIiZI02rJk/MAoJt1DDzAsJ), I may have better luck with an updated driver. I seem to have Mesa 8.0.2 installed, and see from the [Mesa website](http://www.mesa3d.org/) that 8.0.3 is available.

I have added PPA [ppa:ubuntu-x-swat/x-updates](https://launchpad.net/~ubuntu-x-swat/+archive/x-updates), but the only two items it provides for update are xdiagnose and xserver-xorg-video-intel. These aren't the Mesa drivers, are they?

So…

1. Would it help to update my Mesa drivers?
2. If so, how would I go about it?
3. If not, what can I do to fix the problem?

I would be happy to try it out as long as I could roll back the changes should they fail.

More information:

* Ubuntu 12.04 64-bit fully updated.
* Firefox 14.0.1 gives the error
* Chromium 18.0 will not run MapsGL at all (see [post #2](https://productforums.google.com/d/msg/maps/myIiZI02rJk/2l0Qm9ERLj8J))
* **EDIT:** Chromium 20.0 does work if started as `chromium-browser --ignore-gpu-blacklist`. The latest Chromium is available from the PPA `ppa:webapps/preview` (thank you, [mikewhatever](https://askubuntu.com/users/20054/mikewhatever) — see his answer below).
* **EDIT:** Chromium has a setting that works the same way as `--ignore-gpu-blacklist`. Go to `chrome://flags` and enable setting *Override software rendering list*.

Thank you.
