Public bug reported:
Steps to reproduce this bug...
1) Install the current nvidia-340 340.108-0ubuntu2 package.
2) Reboot to confirm nvidia graphics drivers are functional.
3) Reboot and edit the default kernel options to have 'single' before 'quiet
splash'
4) Boot the edited kernel options
The single user mode is broken under 20.04 with the nvidia 340 drivers.
A black screen appears with no single user prompts. If you remove the
nvidia-340 package and reboot, single user mode works as expected under
the nouveau drivers.
I have confirmed with current Ubuntu 18.04 that this bug with the
nvidia-340 drivers doesn't exist and single user mode works properly.
