Screens Not Sleeping

My two screens at work would not go to sleep.

My Nvidia setting had an overlay turned on. Turn it off and bingo.

>This worked until next boot & I'm back to turning them off manually.

Dell XPS 13 Screen Sleeps When Laptop Is Moved

To sum it up. Nothing fixes this problem. Plan to do clean install. 

Dang screen sleeps when I gently move or tip the laptop. It's like the movement triggers the lid closing sensor. If I tip it again it comes back on. After a restart it will be okay for awhile and then it starts again.

I've tried every setting known to man but nothing will cure it long term.

Shutting down and starting does nothing even with fast start turned off.

Restart will cure it for awhile.

Nothing works long term "she's a broke". Must be faulty sensor.
