I'm on an M1 desk, just updated to 3.7 but this has apparently resulted in the loss of functionality for my secondary display through the rear DVI port. How do I get this working as a Multi Monitor?
The secondary display is connected. It "works" to the extent that it is a black canvas to the right of my internal display. I can run my mouse around the secondary screen, but I can't find how to make this space usable? When I go to Menu>System>Display all the displays are greyed out. It seems connected displays should be white text? In it's current state as an extended single display, I don't see any way to setup workspaces in the "working" secondary screen.
