Thank you very much for your guide. I now have brightness adjustment working on El Capitan with HD4400.
Following your guide, I used ACPIDebug and found out _Q11 and _Q12 are the EC methods called for brightness up and down respectively, and by searching for PNP0303 in DSDT I found that KBC0 should be the device name for my keyboard. However, now I am confused by all the keycode stuff. Could you explain what is ADB code and where can I find the appropriate keycode to use? I have ELAN touchpad, and I'm using EMlyDinEsH's driver version 4.6.5.
Read post #1 carefully. The patches/codes required for the ELAN driver are explained.
Some newer versions of the ELAN driver may have direct support with codes 0x10 and 0x20. So, no need for ACPIKeyboard.kext in this case.
Right - Slider works, but the brightness keys are still a challenge.
I followed the guide and enabled the key logging.
When I press the F5 an F6 keys on my vaio keyboard I can see a message in the console all.
F5 AppleP2Keyboard sending key 3f=60 down
F6 ApplePsKeyboard sending key 40=61 down
But when I add the "Fn" key no message appears on the console
