Unable to query number of CUDA devices! Ubuntu 16.04 and GTX 970

[Ethorsen]

Compiled with no problem. Every dependency has been installed/updated.

Ubuntu 16.04 GTX 970

When I start the miner, it only outputs: Unable to query number of CUDA devices!

If I try to force a gpu_config, it gives me the same error but only after trying to connect to pool. Plus an extra: [2017-09-22 09:33:54] : Setup failed for GPU 0. Exitting.

Also tried to build specifying cuda arch with no luck cmake . -DCUDA_ARCH=52
