Install cuda on ubuntu 19.04

install drivers

sudo apt install lightdm

This is required because gdm3 does not work well with nvidia's proprietary drivers but lightdm does. When you install lightdm, there will be a prompt to determine what desktop manager should be the default. Select lightdm.

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt install dkms build-essential
sudo apt update
sudo apt install nvidia-driver-418

Before updating, I like to make sure I'll be able to get back into my system. By default, ubuntu 19 comes with a 0 second timeout on grub. Which is stupid. edit /etc/default/grub and change GRUB_TIMEOUT to something higher than 0. This will allow you to get into recovery mode easily if you break your system.

Then run,

sudo update-grub

to make your changes to the grub config take affect.

Then reboot your system.
