So, installing the experimental packages it will work, but ITS EXPERIMENTAL, i`m stable until now but u can have some problems, so be careful! add to sourcelist: deb http://deb.debian.org/debian experimental main contrib non-free
Than run: - sudo apt update - apt -t experimental install nvidia-driver At this moment, the experimental package is 455.23.04-1. U can have a look here: https://packages.debian.org/experimental/nvidia-driver After installing, it should be working :) If u dont want to use experimental packages, just wait it get out from experimental! Bye :D
