decodernt Posted September 27, 2016 Share Posted September 27, 2016 I have install BrightnessFix on Yosemite 10.10.5 on ASUS V551LA Laptop, but from the boot logo and after, the brightness lowers and never comes back to maximum. When i run BrightnessFix from the terminal it outputs read operation failed, although i reinstalled it with only -b on plist file. I connect a second screen by HDMI and the brightness is great, the problem is only on the laptop screen. I have installed Brightness Slider App, but the max of the slider is the low brightness it already has. I have the Clover boot loader, maybe change some other settings to make it work?

decodernt Posted September 28, 2016 Share Posted September 28, 2016 Hey..somehow i fixed it.. As far as i can remember the steps i took was..Enable again CSM on BIOS, which used to destroy the Resolution and added to the config.plist on EFI, Devices-> SetIntelBacklight=>true and System Parameters -> BacklightLevel=>1.0. For the video Card i have set IntelGFX => 0x04128086 and ig-platform-id=>0x0a260006 which used to work and recognize the Intel HD4400 1536MB graphics card, but not anymore. For this i had to set the resolution of the screen manually for the configurator at 1366x768. During boot i used -v to show up some debugging notes and i noticed that ACPIBacklight and IntelBacklight reported as not found, i don't really worry for that as my brightness has come up again, though i can not control it somehow (have installed shades and brightness slider, nothing works but don't care). Now i have to fix the audio, remains a problem, and the video to work again...any ideas? Am i missing any kexts? Link to comment Share on other sites More sharing options...
rafz Posted April 19, 2017 Share Posted April 19, 2017 Hi guys, I did the install and on boot I can see the brightness fading, alright... But after this, at last, last moment, something happens and back the brightness to max (as default). I supose that maybe is something in launchd that is running after the brightness? Any ideas to solve this? --- DELL Latitude E5250 12.5" Intel Core I7 5600U 16GB RAM DDR 3 Wifi DW1560 SSD Samsung 850 EVO 500GB Link to comment Share on other sites More sharing options...
