SUMMARY *** I own a Lenovo Legion 5 Pro laptop with an AMD Ryzen 7 6800 CPU and an AMD Rembrandt [Radeon 680M] GPU, next to an Nvidia GA106M [GeForce RTX 3060 Mobile one. I use the AMD one. Controlling screen brightness does not work at all when using Wayland. In X11 I can use xrandr to set a value, but in Wayland this does not work: The function keys on the built-in keyboard don't work, hovering the mouse over the battery symbol and using the mouse-wheel doesn't work. I always have 100% brightness. I use the Fedora38 KDE spin. *** STEPS TO REPRODUCE 1. Using the keyboard function keys 2. Hovering the mouse over the battery symbol and using the mouse-wheel 3. OBSERVED RESULT Always 100% brightness EXPECTED RESULT Controllable brightness SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora 38 KDE, kernel 6.3.11-200.fc38.x86_64 (64-bit) (available in About System) KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION
Hi, this bug is not a KDE bug so it can be taken away from here. It turned out it is something in Fedora Linux. After installing a package called "light" I can set, increase and decrease the brightness of the monitor. Sorry for all the commotion.
