ISSUE: My laptop's display is broken, so i removed the in-built monitor (LVDS1-1) and bought an external monitor (HDMI-1-1).
Under Setting, I am able to change display mode to 'Single Display' as my HDMI-1-1. However, this setting kicks in only after I log in.



Before login, ubuntu treats it as dual monitor system and all the text is 'displayed' on LVDS-1-1 (which i can not see, since there is no monitor connected) (I am able to login by entering the password, but it is annoying)



QUESTION: How can I change the display mode to always be as Single Display, even before login?



ENVIRONMENT:
-Ubuntu 18.04
-Nvidia GFX (Switchable mode with Intel)
-New to Linux



THINGS I TRIED:
1. Editing /etc/lightdm/lightdm-gtk-greeter.conf (added active-monitor=0)
2. NVIDIA X Server Settings (Prime Displays cannot be controlled by nvidia-settings)
3. Editing ~/.config/monitors.xml (LVDS-1-1 is already disabled)
