KazWolfe Posted October 28, 2015 Share Posted October 28, 2015 Hello, I am trying to get brightness controls for El Capitan working, but it absolutely refuses to work. If anyone more professional with DSDT has some free time, I'd really appreciate it if someone would take a look and make sure I did it right. I've attached my DSDT work folder containing: Raw (unedited) extracted DSDT and SSDT* AML files Decompiled (and edited) DSDT and SSDT* DSL files. Current (compiled) versions of all DSDT and SSDT* AML files being used Full patch history If someone could take a look, check for errors, patch brightness (or check my work), and just give me pointers as to how to improve my DSDTing in the future, I'd be forever grateful. Thanks! Graphics Card: Intel HD4400 (Mobile) [Haswell] DSDT-SSDT.zip Link to comment Share on other sites More sharing options...
WaldMeister Posted November 9, 2015 Share Posted November 9, 2015 Hi, Graphics device can be found in SSDT6. I'm not fond of SSDT's, so i hope this works. This should enable the brightness slider in system preferences. If you are talking about the brightness hotkeys, please provide more system information. Is it the one in your signature? A clean DSDT was error fixed on ACPI 5.1, no patches applied. SSDT6.zip DSDT.aml.zip Link to comment Share on other sites More sharing options...
KazWolfe Posted November 16, 2015 Author Share Posted November 16, 2015 This should enable the brightness slider in system preferences. Your patch did enable the brightness slider, but it still doesn't actually set the brightness. What could be causing this? Link to comment Share on other sites More sharing options...
