Problem: Failed to initialize NVML: Driver/library version mismatch
dmesg | grep -i nvrm
NVRM: API mismatch: the client has the version
(Symptoms: nvidia-smi weirdness, ~/.zoom/*log weirdness, Zoom crashes)
This fixed it, with no weird mobprobe/grub hand configuration Kabuki:
sudo apt remove --purge nvidia
sudo apt autoremove
sudo apt install nvidia-driver-450
nvidia-smi
