Samsung Chromebook uses software rendering when hardware rendering can work. Please whitelist Software Rasterizer

[Pete Graner]

Chromebook uses software rendering when hardware rendering is working.

I installed raring on my chromebook and unity-support-test reports that it is using hw rendering.

Output of glxinfo

[Daniel van Vugt (vanvugt)]

glxinfo:
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 9.0.1
OpenGL shading language version string: 1.20

This is actually a good thing and we don't want to fall back to LLVMpipe. Because it seems the Software Rasterizer will automatically use LLVMpipe where it needs to. And sticking with it you will still get access to your 2D acceleration provided by the Mali X driver. However forcing LLVMpipe as we do right now is a problem. Because forcing LLVMpipe will not allow you to use the 2D acceleration.

Status changed to 'Confirmed' because the bug affects multiple users.

Is this a similar issue to https://bugs.launchpad.net/chromebook-arm/+bug/1085596 ?

Marked it as affecting me as I believe it to be similar.

@daniel: you need to use es2_info from the mesa-utils-extra package to have the equivalent of glxinfo on an GLES ARM device...
