I have installed cuda8 on my GTX 950m Ubuntu 16.04 Laptop.
Running deviceQuery returned:
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL
I checked and there was no nvidia folder in the /dev/ directory.
whereis nvidia yields:
nvidia: /usr/lib/nvidia /usr/share/nvidia /usr/src/nvidia-378-378.13/nvidia
Is nvidia driver installed already? I tried installing ./NVIDIA-Linux-x86_64-375.39.run, after doing:
kill your current X server session by typing sudo service lightdm stop or sudo lightdm stop
Enter runlevel 3 by typing sudo init 3 and install your *.run file.
You might be required to reboot when the installation finishes. If not, run sudo service lightdm
start or sudo start lightdm to start your X server again.
But it caused a login loop, where I couldn’t login again.
I then typed the following comands:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo ubuntu-drivers autoinstall
sudo reboot
I was able to login now, but I am back on square one.
Is Nvidia Driver not installed? what do i do now?
