Firefox fails WebGL test #11

Closed accetto closed 3 years ago

accetto commented 3 years ago

If navigating to the URL https://get.webgl.org, then Firefox displays the following text:

Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

This is actually not a bug, but a compromise decision taken during development. I try to keep the images slim and therefore I try to include only a minimum of necessary packages.

However, Firefox requires the mesa-utils package to be installed to pass the WebGL test from above. Interestingly enough, Chromium doesn't require that.

Because the mesa-utilspackage adds 143MB to the image, which is almost a half of the base image accetto/ubuntu-vnc-xfce-g3:vnc size, I've decided against it.

There are several ways to get a Firefox image, which passes the WebGL test, if you really need it:

  1. You can install the mesa-utils package in the runtime using sudo apt-get update && sudo apt-get install -y mesa-utils.

  2. You can modify the Dockerfile and built a new image locally.

  3. You can use one of the Firefox images from the Docker Hub repository accetto/ubuntu-vnc-xfce-opengl-g3, because the images from the project accetto/headless-drawing-g3 already include support for OpenGL/WebGL/VirtualGL.

  4. You can use one of the bigger Firefox images of the Generation 2 (accetto/xubuntu-vnc-novnc-firefox) or Generation 1 (accetto/ubuntu-vnc-xfce-firefox-default, accetto/ubuntu-vnc-xfce-firefox-plus).
