My laptop Asus G750JS Ubuntu 14.04 linux kernel 4.4.0 video card Nvidia 870M I can use only driver version Nvidia 340 when I set up new driver from Nvidia I’ll have got a black screen.
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
