AIUI this will only happen if there's an external monitor plugged into the discrete GPU using nouveau. That's common, but hopefully less common than hybrid laptops without an external monitor connected.

So as a workaround you should be able to:

1. Unplug the monitor.
2. Log in using the laptop display.
3. Use the 'Additional Drivers' app to install one of the proprietary Nvidia drivers.

or just use Xorg.
