Without setting acpi_backlight, "echo 100 > /sys/class/backlight/nvidia_wmi_ec_backlight/brightness" gives an invalid argument error. With acpi_backlight=native, "echo 100 > /sys/class/backlight/amdgpu_bl2/brightness" does change the brightness. The brightness keys and sliders in KDE also work (as I mentioned before). -- You are receiving this mail because: You are on the CC list for the bug.
