Inspiron 15 7559 Brightness Key Remap

[2eno]

I successfully installed brightness slider for my Dell Inspiron 15 7559 UHD running high Sierra.
Now I want to map F11 / F12 Key for it. So I followed this guide:

https://www.tonymacx86.com/threads/guide-patching-dsdt-ssdt-for-laptop-backlight-control.152659/

With the ACPIDebug tool I found out:

method _Q81 corresponds to F11 (Brightness Down)
method _Q80 corresponds to F12 (Brightness Up)

I patched the methods to contain

Notify (\_SB.PCI0.LPCB.EC, 0x0405)

and

Notify (\_SB.PCI0.LPCB.EC, 0x0406)

rebooted and the brightness keys are still not working. using rehabmans latest VoodoPS2Controller.
Can maybe anybody have a look at my DSDT.dsl?

Thank You!

Wrong patching.

Got it partially working by using this guide.
means I'm now using EMlyDinEsH's Smart Touchpad driver and patched

Notify (PS2K, 0x10)

to _Q80 method
and

Notify (PS2K, 0x20)

to _Q81 method.

when I boot now, before logging in, the brightness keys are working. As soon as I'm logged in the keys are not working anymore. Though EC queries are still generated, as I can see in the console app.

Any thoughts on why the keys aren't working anymore after logging in? Thank you!

Creating a new account solved the Problem temporary, but after a while (without doing considerable changes) it stopped working again and brightness keys only work in login screen again.

Is there any chance to fix this?

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.
