Ubuntu Nvidea drivers

Using 18.04+ To install run the following command:

sudo add-apt-repository ppa:graphics-drivers/ppa This will automatically update the repositories and then you can run the following line:

sudo apt install nvidia-driver-396

If your desktop does not load after installing the corresponding driver, then do the following:

sudo nano /etc/gdm3/custom.conf

then remove the comment (# symbol) from the line that says WaylandEnable=false and save. Then reboot. If this still does not work, then please disable Secure Boot since you might actually be using UEFI.
