Nvidia driver issue

[Plynx]

Hi all, love the operating system; after seeing it on Retro Recipes I wanted to try it out for myself. I installed it to a partition and got it working, updated the kernel, ran sudo apt-get update and sudo apt-get upgrade and fixed some of the errors I received from repositories, etc.

But when I run the Nvidia driver installer or install nvidia drivers manually, I only boot to a black screen with a blinking underscore cursor at the top left. I have an Nvidia RTX 3080Ti on an AMD Ryzen 9 5900x connected via HDMI to an LG C2 TV. I tried purging, uninstalling, and reinstalling the drivers many times, blacklisting nouveau manually, manually editing xorg.conf, making sure secure boot is off, installing development branch drivers, etc, but so far nothing has worked. I tend to get errors like (EE) [drm] Failed to open DRM device for pci:0000:0a:00.0 -19 or

Ultimately I’m forced to go back to the terminal and restore the open source drivers to get back to the desktop. Any ideas?

The process to follow would be for Debian Bullseye.
