Pop!_OS handles NVIDIA driver updates automatically through its system update process. You should not manually install or click "install" on an NVIDIA driver from the Pop!_Shop if it's already installed. Doing so could potentially cause issues with your system.

Why You Shouldn't Manually Install

The different NVIDIA driver packages you see in the Pop!_Shop are not meant to be installed on top of one another. They are different versions of the driver, and Pop!_OS is designed to select the correct, most stable version for you.

When a new, stable NVIDIA driver is available, it will appear as a system update and will be installed along with other software and kernel updates. The best way to update your drivers is simply to keep your system up-to-date.

To ensure your system is fully updated, you can use the Pop!_Shop or run the following commands in the terminal:

sudo apt update
sudo apt full-upgrade

This will safely update all your packages, including the NVIDIA driver, without risking system instability. Manually trying to install a different version from the Pop!_Shop can lead to dependency conflicts and other issues that can prevent your system from booting correctly.
