Sorry for the title; I didn't really know how to describe the problem succinctly. On a laptop with Plasma 5, if you click the battery icon in the system tray, there is a check box labeled "Allow automatic sleep and screen locking." By default, it is checked. Sometimes I uncheck it if I have a process going on and I don't want the computer to sleep.

As of the last couple updates to Plasma, I've noticed that if I uncheck it and then check it again, automatic sleep and screen locking isn't restored like it should be. I have to log out and back in again to get it working again. This can obviously be problematic if the user doesn't realize it, since it will continue to use the battery and remain unlocked. Can anyone else confirm this behavior?

So, has anyone tried this? It is a pretty easy thing to test. Just uncheck the "Allow automatic sleep and screen locking" box, check it again, and then walk away for awhile and see if the computer sleeps/locks according to the power saving settings.

I've tested and found the same, need to logout and login to get automatic sleep working.
Not only that, also screen dimming, I guess these options all fall under the same umbrella.
Looks like a bug.
