Actually I didn't do 'make install' on the Cubox - I just ran it from the
build directory ( which I had permission to write to ).

Yes I originally was using glxinfo - see my 1st post. Since updating a few
packages, about 3 months ago now, I haven't been able to get glxinfo or
glxgears to run with 3D acceleration. That's what this post is about :)

At this point, I'm thinking of changing tack somewhat. I have 3D
acceleration working under Wayland - and Enlightenment is actually really
smooth during full-screen transitions etc, which is great, but there are
some rendering issues with terminology ( completely corrupted window ). I'm
trying out other terminals and trying to see if I can figure out what
terminology's problem is.
