As the title shows, the monitor of my laptop only works at max brightness under KDE. I have read many articles include the Arch wiki and configured some grub files, but none of them helped. Commands like
inxi -G returns the following:
Graphics: Device-1: NVIDIA GA106M [GeForce RTX 3060 Mobile / Max-Q] driver: nvidia v: 470.63.01
Device-2: IMC Networks Integrated Camera type: USB driver: uvcvideo
Display: x11 server: X.Org 1.20.13 driver: loaded: nvidia resolution: 1920x1080~165Hz
OpenGL: renderer: NVIDIA GeForce RTX 3060 Laptop GPU/PCIe/SSE2 v: 4.6.0 NVIDIA 470.63.01
I have also tried
xbacklight -set 50, it returned normally, but the actual brightness of the screen is not changed. I also tried
echo 50 > /sys/class/backlight/nvidia_0/brightness, it also returned normally but without changing the brightness.
