I am not sure whether this is the right conponent. I can configure the shortcut of adjusting brightness in global shortcut ---- KDE daemon. When I use Fn + F7/F8 on my computer, I can adjust brightness. But this is not accurate. I can control the brightness by /sys/class/backlight/acpi_video0/brightness. Everytime I press Fn +F8, the brightness will increase a lot. From 0 -> 2 -> 5 -> 7. But this is not I want. I think the gap of each level should be 1. Reproducible: Always
