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?
