I don't think the open source NVIDIA graphics drivers support GNOME on Wayland in Ubuntu 16.04 LTS.

That might be true, but NVIDIA isn't mentioned anywhere in this bug.

fcole90: What GPU/drivers are you using?

I have an nvidia/intel hybrid GPU (GTX-850M), with nvidia proprietary drivers (nvidia-375) from the supported drivers PPA. The attempt failed when using the intel GPU, so the nvidia part is not involved. Using GDM I could load a fully functional Wayland session.

I'm using also the most updated Linux/X/Mesa HWE stack from main repository (I think it's based on the 16.10 stack).

OK, could you please:

1. Start a separate VT login: Ctrl+Alt+F4, and log in.
2. Return to lightdm (Ctrl+Alt+F7) and attempt a Gnome login.
3. After it fails return to Ctrl+Alt+F4 and take a copy of the log using this command:
   journalctl /usr/bin/gnome-shell > gnome-shell.log
4. Attach gnome-shell.log to this bug.

I hope in future bug reports will do this automatically for users, but they don't yet.

No journal files were opened due to insufficient permissions.

Retrying as superuser I didn't receive the warning but the log was empty..
