Ok thanks!

Without setting acpi_backlight, only nvidia_wmi_ec_backlight shows up in /sys/class/backlight/

With acpi_backlight=native, only amdgpu_bl2 shows up in /sys/class/backlight/

And adjusting this didn't change the backlight level? e.g. echo 100 > /sys/class/backlight/amdgpu_bl2/brightness

(This is still on nouveau/amdgpu; will test out proprietary Nvidia soon.) -- You are receiving this mail because: You are on the CC list for the bug.
