Public bug reported: The Ubuntu login screen is tiled on all displays, not mirrored, making it nearly impossible to login when using an external monitor if the laptop screen is not visible.
There appears to be no available control to alter the display settings of the login screen. Prior to bionic, the controls followed the mouse onto different displays so you could login by giving the mouse a swipe to the right to get the controls to appear.
