I am using Ubuntu 16.04. This website http://www.webupd8.org/2016/06/how-to-install-latest-nvidia-drivers-in.html mentioned that ubuntu users can now have a simpler way to update it nvidia graphic driver via ppa due to https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa. This is great.
However, i came across this answer from stackoverflow http://askubuntu.com/a/851147 that mentioned that proprietary nvidia driver is still needed when CUDA is required.
Can someone advice me whether CUDA can operate with both open source Nvidia driver and Nvidia proprietary driver, or only with Nvidia proprietary driver? I am currently using nvidia driver 375.39.
