While the nvidia-340 driver works fine from a normal boot, when 'single' is added before 'quiet' in the grub kernel arguments, the boot produces a black screen that never returns the expected single user mode prompts.

nvidia-340 is a very old version of nvidia.

20.04 LTS has: nvidia-driver-390, nvidia-driver-435, nvidia-driver-440.

Can you please use Super to search and launch "additional drivers"
select 440 driver and install and try that one? It is the recommended
version of nvidia on 20.04 LTS. Or whichever is highest and supports
your nvidia card.
