I want to add an ambient luminosity sensor to my desktop PC. Although it’ll require more manual construction than I’m used to, I shan’t be the first to do so. However, I want to ensure that KDE Plasma already support this use-case, probably accidentally.
To this end, I’m a little curious about KDE Plasma’s display brightness adjustment capability:
I realize that to modify a display’s brightness, it needs to use some lower-level (I expect DE-independent) software like
ddcutil, which supports my monitor. However, although I can use separate software like https://store.kde.org/p/2015475 to control its brightness, the native plasmoid enabled by default on a laptop isn’t enabled by default for my desktop, so I’m worried that even if the brightness detector is recognized by Plasma, there’s another kind of incompatbility.
