I try do this https://devtalk.nvidia.com/default/topic/941096/linux/ubuntu-16-nvidia-36x-drivers-black-screen/post/4909187/#4909187
but I will receive the same result(black screen)

problem solved

I’m installed driver from nvidia 367.57 package CUDA 8-0-local_8.0.44-1


I put the packages through dep (local),and added /etc/modprobe.d/blacklist.conf

blacklist nvidia_drm
blacklist nvidia_367_drm
blacklist nvidia_modeset
blacklist nvidia_367_modeset
blacklist nvidia
blacklist nvidia_367
alias nvidia-uvm nvidia-367-uvm
alias nvidia-nvidia modeset-367-modeset
blacklist nvidia_375

and in ~/.bashrc

alias gpucoretemp=‘optirun nvidia-settings -c :8 -q gpucoretemp’
export PATH=/usr/local/cuda-8.0/bin:/usr/lib/nvidia-367/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH

and the problem with the black screen gone bumblebee works even graphics editor blender saw cuda. : - ))))) I’m very impressed
Don’t know why, but when set up sudo add-apt-repository ppa:graphics-drivers/ppa is download and install new driver nvidia_375 and I have been gotten back a black screen also I did not try to block read the modules nvidia-375 still started with X-. back to CUDA and knocked all repositories with the new NVIDIA drivers
