I want to install Nvidia Drivers off a bootable USB. How?

Solution 1:

If you have internet access on the machine, you don't need to install from a USB drive. The recommended method is to use the Ubuntu "Software & Updates" GUI or the APT package manager as it will take care of installing everything for you as well as keeping everything up to date when you update your system. Manually installing drivers will cause the drivers to break when you update your system in the future.

See the link below for instructions. Use the GUI method if you have a graphical desktop or the command line interface (CLI) method if you want to use the terminal. I would not recommend installing via PPA or manually from NVIDIA's website for the same reasons I listed above. https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-20-10-groovy-gorilla-linux
