While this sounds close to bug 2003237, I now realise that might be a different issue.
** This bug is no longer a duplicate of bug 2003237 Monitor does not turn off after idle timeout is reached -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2007268 Title: Wayland/Gnome doesn't DPMS screens on idle/screensaver wasting energy and burning LEDs Status in mutter package in Ubuntu: New Bug description: In the 2022/2023 energy crisis era, this shall not happen. But... I haven't found solution other than "switch to X", which is not an options with my scaling settings for both 4K screens I'm using. On idle when the system blanks screen backlight remains on, wasting energy and burning LEDs in my screens. Please provide solution that would let Gnome set DPMS properly and actually send screens to proper sleep when OS goes idle (enables screen saver).
