though installation of the deb files might actually work, the correct procedure (especially for multi GPU systems), is to go into terminal, do init 3, and sudo ./ the nvidia driver .run files.
Well I got to say thanks again because I’ve used this method three times now. Basically every time Ubuntu updates the NVIDIA drivers subsequently crash and I have to do it again… perhaps it’s time for an AMD graphics card. Any suggestions for one under $100 at supports 4K?
