Boot dmesg output

Hello,

on my old MacBook4,1, using Ubuntu 14.10, it seems that the llvmpipe driver is chosen instead of i965.

I'm attaching the boot dmesg output.

And of unity_support_test -p , in case you need it

What makes you think it's using llvmpipe instead of i965? The unity_support_test output says:

> OpenGL vendor string:   Intel Open Source Technology Center
> OpenGL renderer string: Mesa DRI Intel(R) 965GM x86/MMX/SSE2
> OpenGL version string:  2.1 Mesa 10.3.2

which shows the i965 driver in use.

Interesting.

I'm attaching the unity_support_test that made me (or rather a helpful guy on launchpad, see https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1422163) think that it was llvmpipe.

It was generated on on February. As far as my (limited) understanding goes it looked like the i965 driver failed to load for some unknown reason and llvmpipe was picked up as a fallback.

I re-generated the one I attached when I opened this ticket a few minutes ago, on the same hardware.

Likely something changed in between in ubuntu, you are right, it looks like the right driver is picked up now.

Sorry for the noise.
