I am new to this issue. I have an nvidia motherboard with an internal nvidia video driver with NVIDIA® 780a SLI Chipset. I also added a nvidia K620 video for cuda computing. I started with a fresh install of Ubuntu 16.04. After I installed the video
sudo apt-get nvidia-375 nvidia-modprobe
I wasn’t able to login again. I suspect that the nvidia-375 doesn’t work with the motherboard video and that breaks something. In the past I was able to get the ubuntu to work by Alt-CTL-F1 and purge nvidia-*, but that defeats the purpose.
Once Ubuntu stop allowing me in (login stop working), I don’t know how to control the driver.
I suspect I should use x.org Xserver for the internal video, and some other driver for the K620.
I just want to use the K620 for cuda computations. Do I really need to install a driver to run cuda.
I tried not to do it, but then other items were not installed.
Any guidance would be extremely helpful. Thanks
