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.
