I got similar spec laptop(Lenovo Legion 5) with AMD Ryzen 7 4800H with Radeon Grpahics and NVIDIA GTX 1650 Ti dGPU. When using amdgpu kernel driver, the backlight is registered at /sys/class/backlight/amdgpu_bl0 Now the problem is /sys/class/backlight/amdgpu_bl0/actual_brightness is stuck at 311 and brightness control does not work at all. I've tried a lot of workaround and even booted with the mainline kernel but brightness control does not work. Only Fedora Workstation 32 with Linux kernel 5.6.6 has brightness control working for AMD Ryzen 7 4800H APU which has the Renoir Graphics. I have no idea why amd guys would break a already fixed issue in kernel 5.6.6, I've tried all versions of the kernel but none works other than Fedora Workstation 32 with Linux Kernel 5.6.6 -- You may reply to this email to add a comment.
