GNU/Linux Kali Install NVIDIA GeForce RTX 4090 Driver
How to Install NVIDIA GeForce RTX 4090 Graphics Driver on Kali GNU/Linux desktop – Step by step Tutorial.
The NVIDIA RTX 4090 Kali Driver Setup is a breeze, requiring just a few straightforward Shell Commands to complete.
Especially relevant: currently the NVIDIA 520+ Driver is not available in the Kali Repos.
So here I propose as an available Solution the latest Generic Linux Driver build from NVIDIA.
Again in case of Installation Issue you should priorly see the Upgrade Kernel Guide.
