I see lots of posts about KDE being able to sync the screen with LED backlit keyboards but other than saying that, no information on how to do it or what keyboards are compatible.
I could be totally missing something, I tried to parse through the changelog but didn’t see anything in there about it.
Would anyone be able to explain how I should check if my keyboard (Akko 5108) is compatible and how I can change the settings if possible?
Where did you see this information?
The ability for a screen to sync with something like an RGB backlight would be about the driver. Some RGB lights on keyboards don’t even have an interface controller, meaning they just cycle whatever is programmed into the keyboard controller itself (Lenovo as an example). Are you sure you even have a controllable one?
It’s in the announcement for Plasma 6.1, see https://kde.org/announcements/plasma/6/6.1.0/
To enable it, you need to use the Brightness & Colour widget. See also the merge request for this: https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4093
I guess the documentation is a bit lagging still! I don’t know about a list of compatible keyboards, but I suppose you can just try it out to see if it works! 😁
