Ok, well it's very acceptable, so no worries. Will try to upload the kext.

 

What about my question in #170? You got a working USB 3.0 driver? And maybe even sleep mode?

[Trucker MK]

No for the USB 3.0

For sleep, you need to patch AppleIntelCPUPowerManagment.kext There's a script for this, search this forum for patching AICPUPM

You can start by testing all personalities and if none of them works for LVDS you need to choose one and edit the connector info ( SenseID, Transmitter, Encoder etc)

 

ok

Patched the values of LVDS for pitchecia and ipomoea, tried them both with editing the chameleon conf. The LVDS is still black with no backlight.

This is what i used for lvds:

02 00 00 00 40 00 00 00 09 01 00 00 10 01 00 07

I have never achieved getting backlight working on the LVDS. It detects my GPU as 6400 series with 1024mb which is right. VGA screen working with 1440x900@75hz with customized edid file. When booting without VGA connected i get a kernel panic.

What am I missing?

Try different value for the transmitter.

[Tauio111]

Try different value for the transmitter.

I have tried using the transmitter and encoder values from my bios decode. The LVDS was still black without the backlight.

[Trucker MK]

Have you tried 20 for transmitter?

[Tauio111]

Have you tried 20 for transmitter?

Tried with

02 00 00 00 40 00 00 00 09 01 00 00 20 00 00 07

still black with no backlight.

[Trucker MK]

20 01

[Tauio111]

20 01

02 00 00 00 40 00 00 00 09 01 00 00 20 01 00 07

still black and no backlight

[Trucker MK]

Change ATY,ControlFlag from 0x0040 to 0x0100 and try with Transmitter/Encoder 10 01/20 01

[Tauio111]

still black with no backlight :/ Maybe I need to find another framebuffer? Or edit something in my dsdt?

[Trucker MK]

You can try other framebuffers. Look in mucha's thread for all possible values for ATY,ControlFlags, Transmitter, Encoder. Change one of these and try with all possible combinations for others. And all you can do is try, try, try...

Change the LVDS SenseID of all framebuffers to 07, boot with AtiConfig=framebufferName and see if it makes a difference with some framebuffer.

I had some stuff to do today, ill get my hands on it tomorrow as soon as i can

[Trucker MK]

Have fun man. Take notes of what you've tried and than keep on trying 'till you are out of options. You'll succeed, trust me.

[macsane123]

we just try one by one？ah，it is so boring

i puzzled why the figure dumped out from the bios doesn't work？

[Tauio111]

Tried many framebuffers, some give kernel panic, some have just vga working, some dont work at all, and Pitchecia is the only one which shows that I have 2 screens connected, but both screens are my vga screen. My lvds never got the backlight on.
