There appears to be no way to distinguish between screen lock and blanking the screen

Support Graphics & Display
1

I want to turn the screen off after 15 minutes, but not lock the screen after 15 minutes. However, the settings mirror each other. So if I turn the screens off after 15 minutes in Power, the Blank Screen delay in Screen Lock is set to 15 minutes to lock. If I turn the Screen lock setting to never, then it’s also never in blanking the screen in power. And when I come out of lock, it acts like a bootup by automatically starting all my windows all over again instead of bringing me back to where I had been prior to the lock.

You can probably manually set the blanking from terminal? Display Power Management Signaling - ArchWiki

3

That may be true. Can you tell me what to do to not lock but turn off the screen after a period of time, but don’t suspend?

4

Disable screen lock:
Settings>Privacy>Screen Lock–toggle automatic screen lock off

You can set the screen blanking time there, too, or return to Settings>Power and set it there.

Disable suspend:
Settings>Power>Automatic Suspend>toggle off suspend

5

I’ve done that. I can either not suspend and the monitor is on all the time or I can set to a screen lock in 15 minutes where it completely resets back to boot up mode after coming out of screen lock.

6

Sorry to say that I’m not qualified to troubleshoot yet but learning. I had problems waking from suspend which were resolved by switching from Wayland to X11. For what it’s worth, waking from suspend with Wayland is a problem no matter the distro for me and I’ve tried many. I always have to switch to X11. I’ll step away now and let someone more experienced help you.

7

Did you read that paragraph I linked about “Modify DPMS and screensaver settings with a command”?

Starting point xset q then change things with the commands explained?

8

There is an assumption in that article of a basic competence in what they are talking about. It’s not beginner enough for me to understand and implement, not without most likely breaking my system.
