Comment 3 for bug 1841826

That might be but that doesn't explain why the system goes to the "desktop" straight after pressing the power-button w/o identification.

I disabled "energy mode if laptop-lid is closed" in "Tweak" (for gnome), no improvement.

If I let open the lid for 2...3 cm it workes, but then the login-screen is always in the built-in laptop-screen.
