Actually more important to Mir right now is how your system supports OpenGL|ES.

Can you please run:
    sudo apt-get install mesa-utils-extra
    es2_info

and paste the output from es2_info here?

[Unit 193 (unit193)]

From the installed/14.10 system:
es2_info: es2_info.c:158: make_x_window: Assertion `num_configs > 0' failed.
Aborted

[Daniel van Vugt (vanvugt)]

"es2_info: es2_info.c:158: make_x_window: Assertion `num_configs > 0

Enough said. See enhancement bug 1420581 as a way forward.

[Daniel van Vugt (vanvugt)]

Can you please attach the full output of glxinfo? There are more things I want to check...

Interesting, this is present: GL_ARB_shading_language_100

So there is still hope we can support your system with minimal changes to Mir (and Unity8 might work too). I think we just have to implement enhancement bug 1420581.

Syncing task from Mir.
