New Brightness kext, IntelBacklight.kext

[RehabMan]

I got a LVDS screen, see pictures below.

Most laptops are LVDS. That was not my point.

Perhaps you should compare EDID.

Sorry for misunderstanding, if I remind correctly I have to extract the EDID right? Using Ubuntu? Or is there another way? Perhaps within Windows? What should I compare?

In post #42 you pondered regarding refresh rate selection.

A possible theory this that this is related to EDID.

You should compare EDID from your panel to the EDID of locomacg6.

Please take the discussion to a separate thread. It is off-topic here.

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:

Also, post EFI/Clover folder.

You have two PNLF patches.

Note (from disassmbled patchmatic output):

u430:RehabMan 2 Admin$ grep Device.*PNLF *.dsl
DSDT.dsl:                    Device (PNLF)
SSDT-1.dsl:            Device (PNLF)

The one in DSDT will "win". ... and does not work with ACPIBacklight.kext (only IntelBacklight.kext).

so my solution will be install intelbacklightkext in S/L/E>>> which is done already ?
(also remove aspic blaclikght ket from clover kext?)

And you should fix your ACPI/patched files.
