I installed Manjaro 20.1 and the Grub entry does not work acpi_backlight=native. I still have a message:

failed to start Load/Save Screen Backlight Brightness of backlight:acpi_video0

It works perfectly on the Arch. I don’t want to work on Manjaro.

Why doesn’t it work in Manjaro? Did they change something in configs or kernel?
