HI,
I have until now always used X11 and it was pretty easy to control the screen brightness of the built-in laptop monitor: hover the mouse over the battery symbol in the panel and use the mouse-wheel in in- or decrease the brightness.
Now in Wayland this doesn’t work anymore. I use Wayland since it handles tearing much, much better than X11. I use the KDE spin of Fedora 38.
My computer details are:

Does anybody know how to (easily) control the brightness? At the moment it is at what I think is 100% and especially in the evening that is way too bright. I now close the lid and only use the external monitor which has its own brightness control.
Thanks for your help.
