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).

While this sounds close to bug 2003237, I now realise that might be a different issue.
