Actually, which backlight drivers are being used there? Is it only ACPI or native driver?
And do I understand correctly that, if you switch to Nvidia driver (both mod setting and rendering), the backlight control works via /sys/class/backlight, while the same doesn't work if switching to AMDGPU?
To be exact, hybrid graphics brightness control does not work. Yes using only the discrete graphics card with nvidia non-free software enables me to control the backlight. But when switched to hybrid graphics(switchable graphics) the iGPU brightness control will not work. -- You are receiving this mail because: You are on the CC list for the bug.
