(package nvidia-driver). You may wish to keep the package installed - for

630] [10de:0f00] (rev a1)
The above card requires either the non-free legacy NVIDIA driver (package
nvidia-legacy-390xx-driver) or the free Nouveau driver (package
Use the update-glx command to switch between different installed drivers.

Install NVIDIA driver despite unsupported graphics card? [yes/no]
I somehow fouled up the latest update. After rebooting, the system stopped at TTY session.
Subsequently to purging nvidia from the system, I was able to install xserver-xorg-video-nouveau.
I was trying installing a suitable nvidia-driver via https://packages.debian.org/sid/nvidia-driver but am afraid that all this is out of my depth and request assistance for installing the correct nvidia driver to Netrunner 19.01, thanks.
