Hi Dan,

Yes, the ubuntu core 16 release[1] of artik10 has no support of
graphics/opengl. And there was also no any experience of running opengl
application on ubuntu core 16 of artik10.

But that's not to say we can't support it. Actually, in artik10 linux
kernel[1], there's an experimental mali driver in
drivers/gpu/arm/midgard directory and also there was unofficial
userspace opengl support in samsung's forum[3]. To support them, there's some work to do.

Did you run the oxide-eglfs-snap example on Pi? If so, do you still need
other platform to run opengl on ubuntu core?
