Title:
Backlight does not turn off during screen blanking
Status in mutter package in Ubuntu:
Incomplete
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).
