--- Comment #30 from Paulo Nascimento (paulo.ulusu at googlemail.com) ---
laptop: Lenovo Legion 5, amd ryzen 5 4600h
Graphics:  Device-1: NVIDIA TU116M [GeForce GTX 1660 Ti Mobile] driver: nouveau
           Device-2: Advanced Micro Devices [AMD/ATI] Renoir driver: amdgpu
Kernel: 5.12.0-1-MANJARO x86_64

I have loaded kernel 5.12 and enabled the patch with amdgpu.backlight=0. The
brightness controls Fn+F5/F6 works as well as the controls in KDE panel.

There are still the error messages at boot and shutdown though.
