Hello, Same problem here with Fedora 30. I also had the problem with Fedora 29. I have a HTPC with Pentium J4205 (Apollo Lake),running F30/GNOME/Wayland, connected to a 32" monitor via HDMI. In GNOME settings, auto-suspend is disabled but the "blank screen" option is set to 3 minutes. After 3 minutes of inactivity, the screen slowly fades to black and then the monitor switches to stand-by mode (as expected). But one second after the monitor turns on and displays a blank black screen with the black mouse. The screen will no longer switches to stand-by mode after that. If I move the mouse or touch the keyboard, the black screen disappears, the lock screen shield is displayed and I can go back to a functional Gnome-shell session (no freeze at all). The problem is the same if I lock the screen. I cannot reproduce this bug with the X.org session, it seems to only happened to the Wayland session. I tried with the default intel driver and the modesetting driver but it didn't change anything : problem still here in both cases. Perhaps the bug is related to the HDMI connection ? Unfortunately, I cannot try with another port. I don't know where to find useful logs/infos to share here, if I can help…
