SUMMARY In version 5.22 it has a new name "Inhibit automatic sleep and screen loking" When you press the button, the system will actually stop blocking the screen and prohibit sleep mode. But if you press the button again, turn it off, the system still does not return to power management. It will run all the time until you log out of the session or restart your computer. This error is repeated on the Thinkpad P14s and the Thinkpad X260 previously, this error was also present. STEPS TO REPRODUCE 1. Press Inhibit automatic sleep and screen loking in system tray (icon battery) - ON 2. Make sure that the screen does not lock and the computer does not go to sleep. 3. Press Inhibit automatic sleep and screen loking in system tray (icon battery) - OFF 4. Make sure that the screen *lock* and the computer *go to sleep*.

Works for me with a ThinkPad X1 Yoga (gen 4): with the checkbox unchecked, the screen locks/suspends at the normal schedule, and with the checkbox checked, it does not. Are there any app-specific inhibitions? You're saying that this issue was happening to you in the past with a different laptop? Were you using Plasma 5.22 on that laptop, or was it an earlier version?
Thank you for checking it out. Both laptops are running under 5.22 now (Kubuntu 21.04 + KDE backports) . No specific programs or restrictions are used. The only point I do not install TLP utilities. https://linrunner.de/tlp/ I do not install it because in the case of P14s (AMD), the LAN adapter stops working correctly. Yes, the same problem was on earlier versions. I have to use Activities with special nutrition conditions when I need the laptop to stay awake. This is the wrong way, I know, but otherwise you have to log out of the session every time. I tried this feature even on the system immediately after installation, the same thing. I don't understand where my mistake can be. Still simple, click and it works. And I'm sorry that there are no technical details, although I have been using Linux for more than 10 years, but as a user, not a developer.
Thanks for the info. We have another report in Bug 438698 from someone with the same chipset, so it's possible that it's a bug particular to that hardware. It will need investigation with someone more familiar with the power management stuff that I am (which is to say, at all).
*** Bug 438843 has been marked as a duplicate of this bug. ***
Two reports of this now; marking as confirmed and VHI regression even though I cannot personally reproduce it, because clearly other people can. :(
I also cannot reproduce. Please confirm no other processes are running that could be inhibiting screenlocking themselves. After that please can you set the screensaver timeout and record 1 minute of `dbus-monitor --pcap`
