Screen blanks instead of power off

[Tai...@gmx.com]

I have tried all the options in the power control menu but my screen
still doesn't turn off it just disconnects the output so the screen will
say "NO VGA/DVI DETECTED" when power save mode turns on.

Ideas?

issue: Samsung ATIV Book 9 Plus does not power off
Qubes 3.2:

I already tried shutting down all qubes first and then "sudo shutdown now". If I press arrow up I can see the output which ends with shutdown reached. But the screen does power off and the system stays on. How to solve that problem ? I need to shutdown manually by long pressing power button then.

Have you tried 'sudo shutdown -P now' or 'sudo poweroff'?
