Try these steps:

$ sudo apt-get purge nvidia* # remove current installed nvidia software including drivers
$ sudo ubuntu-drivers devices # verify it sees your graphics card
$ sudo ubuntu-drivers autoinstall # install drivers automatically
$ sudo reboot

This is everything I ended up doing which eventually fixed it for me:

# Update repo
sudo apt update

# Remove amdgpu drivers
sudo apt purge xserver-xorg-video-amdgpu
sudo apt purge libdrm-amdgpu*
sudo apt purge libdrm-amdgpu1

# Blacklist the amdgpu driver since we are using nvidia only
echo "blacklist amdgpu" | sudo tee -a /etc/modprobe.d/blacklist.conf

# Remove nvidia driver and install from system76 repo
sudo apt purge *nvidia*
sudo apt-add-repository -y ppa:system76-dev/stable
sudo apt install -y system76-driver-nvidia
sudo apt upgrade -y
sudo reboot

I’ve been wanting to tinker with NixOS. I’ve stuck in the stone ages automating VM deployments on my Proxmox cluster using ansible. One line and about 30 minutes (cuda install is a beast) to build a reproducible VM running llama.cpp with llama-swap.

Do you gave an nvidia graphics card? The only problem I’ve had since I installed Pop OS is their shity driver installer crapped out somehow and I gad to recover my system by blacklisting amd graphics driver, uninstall nvidia driver and reinstall. It wad not for the feint of heart.

A lot of times it is necessary to build the container oneself, e.g., to fix a bug, satisfy a security requirement, or because the container as-built just isn’t compatible with the environment. So in that case would you contract an expert to rebuild it, host it on a VM, look for a different solution, or something else?

reproducing those installs from scratch + restoring backups would be a single command plus waiting 5 minutes.

Is that with Ansible or your own tooling or something else?
