Installing and configuring nvidia drivers in clean Elementary OS 6.x install, including gamemode and prime-run (if indemand)

gistfile1.txt

To install nvidia drivers (based on 515.48.07 at the time of writing) in a clean elementary os 6.1 Jolnir install. DON'T use the driver listed in the eos store.

// Install the toolchain
sudo apt install build-essential
sudo apt install software-properties-gtk
sudo apt install software-properties-common
sudo apt install linux-headers-$(uname -r)

// Install the drivers
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo dpkg --add-architecture i386 
sudo apt update && sudo apt upgrade
sudo apt install nvidia-driver-510
sudo apt install libvulkan1 libvulkan1:i386 // if you have a vulkan capable gpu

// Missing 32bit? install cuda may help

//If nvidia-smi results in NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running:
sudo dkms remove nvidia/515.48.07 --all
sudo dkms install --force nvidia/515.48.07 -k $(uname -r)
sudo update-initramfs -u
sync
reboot

// Check it's working
sudo prime-select query
nvidia-smi
nvidia-settings // don't recommend using this on a hybrid system but it's useful to detect the driver is working
sudo modprobe nvidia
prime-run glmark2

// For on-demand mode
sudo prime-select on-demand

// If the nvidea OR linux version updates and the driver fails, or you get stuck at command/terminal prompt when booting
sudo apt purge linux-headers-$(uname -r)
sudo apt install linux-headers-$(uname -r)
