JomanJi Posted March 1, 2015 Share Posted March 1, 2015 I want to get native brightness on my Asus TP300LA. I applied Brightness fix (+ Haswell, since Intel HD 4400 graphics), as well as rename PCI0.GFX0 to PCI0.IGPU to the DSDT & relevand SSDTs (Happens to be SSDT2 & SSDT7). I tried without the rename patch, with still no luck. I also tried installing ACPIBacklight from VietnamTool, and it loads when I rebuild cache, however still no luck. Inside settings, while the screen's name correctly displays "Built-in Display"; the icon for the screen is not a Macbook screen, but rather a regular monitor screen, like this: So I'm currently stuck with shades. I'd like to get native brightness working for better power management.

styrian Posted March 1, 2015 Share Posted March 1, 2015 Hello! You have to get your display get recognized as built-in to make the brightness control working. First step for this is to use a SMBios of an Apple laptop device. Perhaps you also have to add some properties for IGPU to your DSDT/SSDT´s. Have fun.

midi-sama Posted March 20, 2015 Share Posted March 20, 2015 Try other patches, or just add pfln device, send over your patched DSDT but w/o the brightness patch. Btw, got the touchscreen to work?
