The laptop display works!
When I start up my laptop, you can see the cycling on the laptop screen without it plugged into an external source.
However, when it's time to log in, if the laptop is not plugged into an external source the screen sits there black/gray (but noticeably on).
When I plug it into an external monitor via HDMI cable, the laptop display comes on and so does the external display monitor. The laptop display is display number 1 and hosts the main desktop. However, when I disconnect the HDMI cable from the laptop, even if on the Nvidia control panel it is selected as the main source, the laptop display disappears again and the screen goes black.
I've tried everything I know how to do, does anyone else have a clue?
(It also does this when I boot it into safe mode)
