My laptop is set to turn the screen off after about five minutes, but for the past week or so, once this happens, I can no longer get the screen to come back on. The laptop doesn’t seem to be sleeping (the power LED is still solid), but once it happens, manually restarting the laptop is the only way to get it to come back on.
Is anybody else having this issue?
I have a similar issue under Linux Mint Cinnamon. If the laptop enters s2idle while displaying a virtual desktop which has no application windows (just the normal DE panel and menu windows) it will do as you describe.
To regain control, I switch to tty1 (Ctrl-Alt-F1), press enter and wait for the login invitation to be displayed. Once that happens, I switch back to tty7 (Ctrl-F7) and the lock screen appears.
NOTE: tty7 is the conventional Debian family DE display. I have no idea whether it’s the same on Red Hat systems. Almost certainly someone who knows will chime in.
I’ve trained myself to always leave the lappy parked on a virtual desktop with open windows. Sounds onerous but hasn’t proven to be. Consequently I’ve not dived down the rabbit hole of investigation.

PS: there’s nothing special about tty1. Mint only enables tty[12]. Either screen works as a vehicle for regaining control.
