I have some trouble patching my DSDT to get my brightness working. I tried to patch my DSDT (thanks again for RehabMan for compiling the DSDT for me). I followed the tutorial made by "ivik" at http://www.insanelymac.com/forum/topic/236835-updated-2012-genericbrightnesskext/. I tried both versions. None of them worked. I am wondering if I am doing something wrong.
From what I understand in the instruction, I need to input the code to my DSDT. I have no experience in programming. I am wondering what is the best way to input the code in DSDT editor. the format of the code from the aforementioned tutorial seems to be off. Do i reformat the code of I can just copy and paste?
Also, the tutorial aforementioned stated " ...you should find that device in dsdt. Under that device, there are other devices (usually LCD, CRT, TV...). Look for the device that has those methods (_BCM, _BCQ and _BCL) ". I cannot find any of these terms in my DSDT. I am not sure of the reason. Is that because of my GPU? I also read that in order for brightness to work, the display0 should be AppleBacklightDisplay. but I only have AppleDisplay
I am currently using a intel HD 4600 GPU. the GPU is recognized, but with only 64mb of vram. I tried different Intel Azul FB value with GraphicsEnabler=Y , and none of them worked. and my scroll bar keeps flickering when I scroll. Similar thing happens in Launchpad.
Any help or would be appreciated. My DSDT, along with my IOReg and IOService screenshot are attached below.
