KDE Wayland Screen Energy Saving Problem

cross-posted from: https://lemm.ee/post/6037703

Hi everybody.

I was trying to make the switch to Wayland, but this little problem is really keeping me in X11.

The display turns off, says that there is no signal/input, turns off again but after that it wakes up immediately.

This happens either by using the shortcut to turn the display off Ctrl + Alt + D or waiting for the 10 minutes specified in the Energy Saving options.

I've found this Bug 462695 at KDE.org where it says the problem is from openSUSE.

I've already disabled KScreen 2 in Background Services.

In X11 the display has no problems entering energy saving mode.

Does anybody have the same problem or any idea what it might be keeping the display from sleeping?

My specs:

  • openSUSE Tumbleweed
  • Kernel 6.4.11-1-default
  • DE: Plasma 5.27.7
  • CPU Intel i5-4670K
  • GPU AMD ATI Radeon RX 6750 XT

  • Out of curiosity, does this problem occur if you booted a live environment of another distro? Like does it still exhibit with Kubuntu 23.04's Wayland session?

  • Have you tried switching off the energy saving option

  • OpenSuse tumbleweed user here. Doe this happen when it's time for the screen to go to sleep ? I think I have this too yeah but to be honest I have to check if this is only on Wayland or on X11 as well. But yeah it's annoying.

    • Yes, it happens when the screen tries to go to sleep or when you use the keyboard shortcut to turn it off.

      If it happens in X11 just disabled KScreen 2 in Background Services.

      I've filled a bug at suse. Let's see what they say.
