This bug doesn't exist on the same hardware (a 2008 MacPro with Mac ROM'd GTX680) under current Ubuntu 19.10 with the nvidia-340 package installed. In that case, booting the default 5.3.0-46-generic kernel in single user mode produces the expected prompt.

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.
