Hello everyone, my laptop is not increasing or decreasing the brightness of the screen, before and after upgrading to the Manjaro Ornara [Plasma KDE] version. This is since I installed Manjaro Plasma (without internet on that day, but then I updated the system with the command “sudo pacman -Syyuu” in later days, but it still didn’t solve it.)
Here is a screenshot showing me decreasing de brightness, but not changing nothing on laptop screen
