[Fixed][Waiting for implementaiton] Brightness keys aren't working

[kvn1351]

Please fix the brightness control, so that we can use the hardware keys to control it.

Everything else works great, thanks a lot!

OS version: 10.13.3

You can easily enable brightness keys by using the FN+F4 and FN+F5. You have to go to Settings->Keyboard->Shortcuts->Display and check Decrease/Increase display brightness. Double click next to Decrease/Increase display brightness and press FN+F4 / FN+F5. Now you can Control Brightness easily with these keys(I hope that helps).

@gplast Thanks a lot for your answer. I already knew of this workaround, you could also use BetterTouchTool to get it even nicer (without FN), but I wanted to file a report of this bug nonetheless.

It's not a big issue, but it would be nice if it could get sorted.

Edit: I was wrong. You have to use FN cause the buttons aren't registered at all. I thought that they were at least registering something. I've fixed it though with a patch, read below.

Okay, i use BetterTouchTool to control play/pause but i will give it a try. Thank you.

I've managed to patch the ACPI to fix the brightness keys. However it's a static patch, i.e. a patched DSDT.aml. It works great and all, but it would be cool if I could create a hotpatch of it instead.

I'm not experienced enough with SSDT hotpatching though, so if there's someone who could help with some "External" declarations, please send me a message.

The patched method is huge and contains tons of references that have to be declared, I've fixed most of them, but some are still acting up..

Now I'll try to fix the HDMI issue.

As for brightness keys, I tried changing the default keymaps (f14/f15) to f4/f5, and the brightness control is working as well. I can't quite tell the difference between these and the native keystrokes (fn+f4/f5).

Appreciate you guys' hard work, thanks!
