ok heres my updated status.

laptopdisplay.kext loads perfectly and detects my display and loads to desktop just fine.


once i put in titan.kext, everything loads fine and titan detects my graphics card. But it loads to a black screen with the OS running in the background.

We're getting very close i think.


heres my ioreg file

thanks

I also got a white screen with LaptopDisplay.kext.

These are my system and ioreg log.

I believe you will solve this problem, np_.

Thanks again.

LaptopDisplay.kext - sytem loads, but laptop internal screen is as it was before - BLACK.

Some more tweaks needed, hope we'll find the answer.

[np_]

looking at ioregs seems will need more work

is all because "LaptopPanel" class did not find corresponding DisplayVendorID-*.plist (System/Library/Displays/Overrides/**** ( all display info there is for AppleDisplay's hardcoded and one for "Generic ( any vendor ))

and there is no match

i can tell you from now, laptopdisplay.kext will not work with titan because there are key's need to be set in order ( but with natit + all property's need yes )

video driver to known that video card is "on boad" ie "build-in"

without that key onboard video card is treated  like any other video card

and off course there will be "black screen" , "white screen" ..etc

now this even do not depend on EDID info

i have few ideas to make all this work and i will test under weekend

np_

ps: i need more ioreg logs from ATI on board video cards too

[np_]

ok i will ask you to test laptopdisplay.kext and provide ioregs

but without any titan or natit , even without any apple video driver

just IOGraphics and IONDRVSupport

thanks

Ok, I will post my IOReg-output at 5 pm (its 3 pm here)...
So delete/move all other graphics kexts except iographics and iondrvsupport??

Edit: I have a Radeon 9600 Mobility

So, we have to remove Geforce.kext, GeforceGA.plugin,
NVDANV30Hal.kext, NVDANV40Hal.kext, NVDAResman.kext and Titan.kext or Natit.kext
and then, generate ioreg -l -w 1024 > ioreg.txt right?

Here is my IOReg output! Hope it helps you np_

Great work, np_.

This is a very bright method to solve this laptop problem.

I do like to help test this .
But i think you'd better write down the whole test process.(how to try, what is the good outcome, how to get the IOREG.)

thx...

[np_]

thanks for ioreg's helpful info

i got some "crazy" ideas i will test latter

[Nebzar]

Here are my IOregs.

Thinkpad T60, ATI Mobility X1400, only LaptopDisplay.kext, IOGraphics and IONDRVSupport; removed any apple video driver and Natit.

LaptopDisplay appears among loaded extensions, but no resolution change nor CI/QE.

Best regards and thanks for your work

ok seems i need to build proper DisplayVendorID-XXX info for any laptop

and incude into LaptopDisplay info.plist ( by replace all "ApplePanels" with proper LCD vendor ID)

that for i will need your laptop manifacturer, model and Internal LCD EDID ( from where i will get info to build proper DisplayVendorID )also max resolution suppored

example :

TOSHIBA:  Satellite P20
"EDID" = <00ffffffffffff001e6d474e6a500000091001036a2b1b78ead105a655479d25155054a76b800

max res : ????
/////////////////////////////
( based on Fernando Birra laptop ioregs but i am not sure is internal LCD EDID or external display - FB please confrim )

from EDID, display vendor ID = 1e6d ( toshiba vendor !? )
display product ID  = 4e47

that for will need into System/Library/Displays/Overrides folder with name DisplayVendorID-1e6d include file DisplayProductID-4e47

thanks

ps: maybe need applicaition where user paste his LCD EDID and create DisplayProductID for him ...

video card model do not import if is ATI or NVIDIA or whatever else they put these days into laptops

np_ that seems to be my external monitor EDID information. One curious thing is that it is slightly different from the one I get by connecting through th DVI port.

Through analog port I read 1e6d (vendor = LG) and productID=4e47
But from DVI port I read 1e6d and 4e48 (different product ID).

Anyway, my real laptop EDID is this one:

The lcd is listed as device NVD0900 (in ACPI part of BIOS) and the model seems to be something like "Nvidia default panel" (from EDID information). My max display resolution is 1440x900 but I can't find that information on the EDID.

I am willing to write the application to convert RAW EDID information into the file format you need. All I need to know is where to get the information and what to write

By the way, what is the method to get the display resolution from a panel? Your macvidia driver gets that information and I always thougtht it could be taken from the EDID. However the application that I used to get my EDID (Riva tuner) isn't capable of determining that information from the EDID. Some applications even show 0x0 resolution based on what they get from the EDID. Perhaps the monitor timing information is blank in this case. At least there are 128 zeros at the end

Thanks again np_

[Nebzar]

The display of my Thinkpad T60 is a 15 in. "Wide viewing angle and high density display" with max resolution 1400x1050; video card is the ATI Mobility X1400.

In the Windows device manager the internal LCD appears with these id's (I leave the italian strings of Xp, in order not to make translation errors):

However, these are the EDID bytes for the plug and play monitor:

One strange thing about the EDID data of the plug and play monitor is that within Phoenix the last two characters appear as "2A", while once exported they become "29".

Hoping to be useful, best regards and thanks for your work.
