there is one thing bugging me with linux.
On Windows my secondary displays quickly turn off the backlight when they are empty. By empty I mean that there are no open windows and the wallpaper is plain black. I really love this feature, because it helps me to focus on the main screen. Great for gaming or watching Videos.
I was under the impression that this is an energy saving feature of the monitor itself, since my old displays did this almost immediately and my current ones do it after around 10 seconds.
Apparently it is software related though. It didn’t work on Linux. (Manjaro live)
How do I get this feature on Linux?
