sudo apt-get purge nvidia* libnvidia*

Wouldn't that leave me with no user space video/opengl drivers? After purging immediately reinstall mesa?

You'll already have Mesa. You don't need to reinstall it. Depending on how new your Mesa is, you might want a newer one from Kisak's PPA.

Even if you installed the Nvidia drivers, Mesa is still present on your system, it was not removed. It is just not used.

I think Nvidia binary drivers might do something messy with modprobe configs too. You can check in /etc/modules, /etc/modprobe.d /etc/modules-load.d and etc. Make sure nothing lingering is set there.

Check also your grub boot line. Nvidia installer can modify that too.

If you are using Xorg, you'd also need to remove config file generated by Nvidia for it.

You'd have Mesa, but you might be missing AMD firmware which is necessary for GPU to work. You can install latest one manually or look for a package for it. In Debian / Ubuntu it's firmware-amd-graphics but it's usually pretty outdated and upstream versions are preferable.

To update it manually on Debian based distros, you can do something like this:

#!/bin/bash

base_dir="$HOME/archive"
firmware_dir="linux-firmware"
firmware_branch=${firmware_branch:-"main"}

mkdir -p "$base_dir"
cd "$base_dir"

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git "$firmware_dir"
cd "$firmware_dir"
git checkout "$firmware_branch"
git pull --rebase --prune

sudo cp -v amdgpu/*.bin /usr/lib/firmware/amdgpu/
sudo chown root:root /usr/lib/firmware/amdgpu/*.bin
sudo update-initramfs -u -k all

Thank you for the help,everyone. The command worked.

Shmerl, I'll look into it. But, the kernel messages
are not reporting any missing firmware
