Main laptop screen black

Hello,

I recently bought an external screen, i want to branch it on my laptop.
It was not detected, so I update to latest 440 drivers. Now only the
external screen works, the laptop screen is black.

Could you please help me ?!

It’s an AMD/Nvidia combo, this needs some tweaks. Please delete /etc/X11/xorg.conf first, then follow this:
