Bug Description
After the screen turns off (for inactivity, screen lock, etc.), mouse or keyboard input won't bring it back. When I come back to the computer to resume my work, I have to wake the system up, and press the power button on the monitor. If I don't manually bring the monitor back on, the system will resume and the screen will remain off.
I believe this is a regression, because this cannot be reproduced in distributions as old as Debian Stretch 9. Any distribution newer than Debian causes this problem, no matter what Desktop Environment, what Display Manager or Screen Locker I choose. This is also not reproducible on Windows 10.
It's worth mentioning that this desktop runs the RX 560 AMD graphics card.
Also, this is my monitor: https:/
