Install Nvidia driver (Ubuntu 20.04)

1. Check the Graphics Card and Compatible Drivers for Installation.

ubuntu-drivers devices

2. Install nvidia-driver.

In my case, I will use "nvidia-driver-535"

sudo apt install <Driver Name (ex.nvidia-driver-535)>

sudo reboot

2-1. There is also an option for automatic installation. However, I prefer installing the version I want.

sudo ubuntu-drivers autoinstall

sudo reboot

2-2. Occasionally, I encounter an error message like this: 'I: The initramfs will attempt to resume from /dev/sda2 I: (UUID=7c562eed-5782-45e6-8acd-e99d2cb20d8e) I: Set the RESUME variable to override this.'

echo "RESUME=UUID=7c562eed-5782-45e6-8acd-e99d2cb20d8e" | sudo tee /etc/initramfs-tools/conf.d/resume

sudo update-initramfs -u -k all

reboot
