My laptop's monitor does not work any more and thus I've attached an external monitor.
On boot, GDM still recognizes the primary laptop screen and displays it's login window on it. Which I then can't see.
I can disable the laptop's screen by running xrandr --output LVDS1 --off
after logging in.
I tried putting this command into ~\.xinitrc
and into a ./40-xrandr.sh
in /etc/X11/xinit/xinitrc.d
.
Both to no effect at all. I had hoped that it'd at least would switch off the laptop's screen on log in.
How do I disable the laptop's screen before GDM starts?

). What are the options available under Video? There are so much variations in BIOSes that one can't pinpoint exactly what option to use unless one looks at it. And the terminologies/descriptions used by the manufacturer are quite often inadequate, confusing or misleading.
