How to install CUDA 9.1 on Mint 18.3?

Question

I'm running Linux Mint 18.3 with the Cinnamon desktop environment, and I want to install CUDA 9.1 and NVIDIA drivers. How can I do that?

Solution

I have cuda 9.1 installed on Minty 18.3 with nvidia 387 390 drivers.

This is what I did:

1. Use the driver manager to install nvidia 390 387 (for some reason, 390 isn't working). Note the pic shows 387, but 390 works now.

   

Get the nvidia repo from:

wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1704/x86_64/cuda-repo-ubuntu1704_9.1.85-1_amd64.deb

Install nvdia's repo and repo key for ubuntu 17.04:

sudo dpkg -i cuda-repo-ubuntu1704_9.1.85-1_amd64.deb
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1704/x86_64/7fa2af80.pub

Update apt's software index

sudo apt-get update

Install cuda

sudo apt-get install cuda

Edit: one other thing. If you build the samples, you need to set GLPATH environment variable to /usr/lib: export GLPATH=/usr/lib before you run make in the samples dir.
