Chimera 3.0.1 boots Aspire E1-572 with Low Screen Brightness

[marrioo]

Hi Tonymac,
I have installed Mavericks 10.9.3 on Aspire E1-572. I used MultiBeast for Post installation with DSDT Free and Chimera 3.0.1

What's Working:
Audio: with HDAEnabler and LayoutID=01000000 (I also used HDAEnabler kext in S/L/E)
Battery: with VoodooBattery.kext
WIfi: with replaced AR9285 wifi card (pci168c,2b), inserted in IO80211Family.kext
Ethernet: "Ethernet BuiltIn=Yes" (pci14E4,16B3) using BCM5722D.kext
Intel HD Graphics 4400: with Chimera 3.0.1. This is where the Low Screen Brightness is.

Note: I replaced Chimera's boot file in "/" with Chameleon's and Encoch's bootloaders boot file", but only got VESA resolution. "1366x768x32".

ONLY Chimera's 3.0.1 boot file got Intel HD 4400 working. This setup is DSDT FREE.

I extracted my DSDT and patched with pnlf patch but only got the slider. No brightness change. I Deleted DSDT.
The rig runs well, except for low screen brightness.

So, my question is, how can I get the screen brightness up and, can you edit Chimera to increase screen brightness.
Can you help.

Haswell Brigthness Fix:

You will need to extract all DSDT/SSDT from Linux. Your GFX0 device is in one of the SSDTs not DSDT and to get a proper disassembly of your DSDT (and the SSDT that has GFX0) you will need all of them. They are available in /sys/firmware/acpi/tables and /sys/firmware/acpi/tables/dynamic.

Place all SSDT/DSDT in a single directory and use a recent build of iasl to disassemble:
http://www.tonymacx86.com/attachmen...5-buggy-dsdt-asus-q501la-help-needed-iasl.zip

cd "to directory where you placed all SSDT/DSDT"
iasl -da *.aml

Then search the resulting *.dsl so you know where GFX0 is defined.

Laptop repo: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Rename GFX0 to IGPU" (to both DSDT and the SSDT that has your GFX0 device)
Apply: "Brightness Fix (Haswell)" to SSDT with GFX0
install: https://github.com/RehabMan/OS-X-ACPI-Backlight

Place patched DSDT.aml in /Extra/dsdt.aml. Place patched SSDT in /Extra/ssdt-1.aml (assuming you have already generated SSDT.aml for CPU)

Result: Working brightness slider in SysPrefs->Displays (mapping of keyboard keys is a separate issue), possible LID sleep, and IGPU power management.

Hi Rehabman,
Thanks very much.
I followed the steps you outlined and you were correct as usual.
DSDT compiled. The SSDT4, has the GFX0. (They were seven SSDTs in all.

I also used "BlinkScreen fix" from "HP Probook Installer 6.1" (not the newest one)
Thanks again.

To the person who has the same setup as I am. I am attaching the files (ZIP)
Use at your own risk. I don't have links for the files. But credit to Rehabman of course, and others who worked on these kexts.

Blinkscreen is unecessary with this brightness fix.

And, I'm RehabMan, not Tony...

Ok...Copy.

DSDT works!

Audio: Best result with patched AppleHDA. Google 'patch AppleHDA guide'. Search for suitable AppleHDA or patch it yourself. Apply appropriate DSDT patches.

DSDT patches you need for AppleHDA: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Audio Layout 12" (change layout-id from 12 to the layout-id used by the patched AppleHDA)
Apply: "IRQ Fix"

Ethernet: What Ethernet chipset do you have? Use DPCIManager->PCIList to find out.

Hi RehabMan thank you for the quick reply and help.
I have tried doing what you have suggested but still can't make the sound work.
My h/w details suggest it's a alc282
H/w details: HDAUDIO\FUNC_01&VEN_10EC&DEV_0282&SUBSYS_10250775&REV_1000
DCimanager shows null codec


for ethernet i have used BCM5722D.kext with <string>pci14e4,16b3</string>

H/w details:\VEN_14E4&DEV_16B3&SUBSYS_07751025&REV_01

Search for AppleHDA for Realtek ALC282.
