[solved] Remapping brightness keys

[EverythingIsRed]

My laptop uses ACPI methods to for the brightness keys. However, both keys only end up increasing brightness.

Method (_Q63, 0, NotSerialized)
            {
                Notify (PS2K, 0x0406)    //Brightness down
            }

            Method (_Q62, 0, NotSerialized)
            {
                Notify (PS2K, 0x0405)   //Brightness up
            }

How do I determine the correct value for brightness down?

It's a known issue in Sierra.

You could send F14/F15 instead:

Method (_Q63, 0, NotSerialized)
            {
                Notify (PS2K, 0x0365)    //F14
            }

            Method (_Q62, 0, NotSerialized)
            {
                Notify (PS2K, 0x0366)   //F15
            }

Works perfectly! Thanks!
