I used the following commands to install
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
sudo apt-get install nvidia-384
Installation appears fine with no errors, but I don’t see any NVIDIA folder under /dev.
When I run smi,
modprobe: ERROR: could not insert ‘nvidia_384’: No such device
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
How do I correctly install the latest NVIDIA driver correctly?
