Yes, the default is the nouveau driver, if you want the proprietary driver instead you have to install them, via the "nvidia-driver" package (which will blacklist nouveau among other things). I followed the chain of dependency to double check, and nvidia-cuda-toolkit definitely does not depend at any point on nvidia-driver. If I understand correctly, you do not have the nvidia drivers installed at all, then? I thought they were needed to run cuda applications? Sorry, I'm slightly confused :-) Kind regards, Luca Boccassi
