Thank you for your bug report, the screen configuration change only
apply to the user session and shouldn't impact the login screen. Is your
monitor on? Are you sure the password entry isn't displayed on it? if
you move the mouse can you bring it to the laptop screen? what happens
if you just type enter, your password and then enter again?

Stuck on welcome screen when attached an external display with laptop
Status in gdm3 package in Ubuntu:
Incomplete
Bug description:
I faced this issue on Ubuntu 20.04. My system is fully updated, no
update is pending.
Steps to reproduce
1) Attach an external display with a laptop
2) Set external display as primary
3) Select only single display option
4) Restart your laptop while external display is attached
When the first ubuntu screen is displayed after restart, before login
screen. The system stops there, ubuntu logo with round circle
animation works, but system does not proceed to login screen. I have
waited for about 15 minutes but it did not proceed to login screen,
instead it showed round circle animation with ubuntu logo. Then I
forcefully turned off my laptop by holding down power button. The I
detached my external display and it worked fine. I have faced this
issue many times.
