First tell us if / test this.  Are both OpenCL and Cuda known to work
on the same box with any other application (other than what nvidia
provided, which might show a false positive).  There are many issues
people have when getting 3D working on linux machines and Mathematica
channel isn't a place to ask linux X 3D questions.

... and it could still be a linux library issue.  that's a big
possiblility.  when linux hacks the way (ie, the way a driver loads)
then Mathematica can't talk to a driver, it might crash a forked
process's stack, and in the front end look like "returned false".

With little info there's hardly a way to say more yet.

by the way just because nvidia says "~ that enables dramatic increases
in computing performance by harnessing the power of the ~" doesn't
mean it's true :)  They want you to do CUDA not OpenGL, GL, which is
another story, you have no choice anyhow :)

have you tried raytracing?  very slow but splendid output.
