As i see U're using laptop for OSX, so this kext is for osx determining Your laptop internal display, do You have this problem? Others (also and me) using only external display to see any picture on the screen, because native laptop display not recognized and in BLACK! :2cents:

A note though: the DumpEDID reported max resolution is definitely wrong, as this is a 1440x900 display.

 

Thanks np_!

ok here is for test LaptopDisplay.kext

 

it "should" work on any laptop nevermind what video card is

 

if work you should see class "LaptopPanelA" attached to "IOPanelDevice" in root device tree ( under IOACPIPlatformExpert )

 

also there should be IOBackLightDisplay class set for current display not "IODisplay" !

 

please test and report and do provide ioregs

 

thanks

 

compiled kext:

source code:

 

ps: ( read my notes in LaptopPanel.cpp for future hacking )

I'm a little noob, but... where i should see these classes?

I've installed this .kext and Natit ATI Auto, but Natit doesn't work...

Someone correct me if I'm wrong but I believe we can all stop posting EDID information from our latptops as np_ is writing a program that will translate EDID files into the required format.

Then we can do it ourselves rather than overloading np_ with the job. The files posted so far should be enough for him to fine tune the application.

ok here is new app "DisplayUtility"

 

unzip anywhere you like

 

start it

 

copy your EDID first block ( look like 00 FF FF FF FF FF FF 00 4C A3 55 31 00 00 00 00 ) ( spaces will be removed)

 

paste to DisplayUtility EDID: line

 

push "parse button"

 

and then "create button"

 

you should have now folder with name "DisplayVendorID-"(ur vendor 4 chars hex ) and file inside called "DisplayProductID-(your display product hex 4 char ) in same place "DisplayUtility.app" is located

 

copy that folder with file inside to location /System/Library/Displays/Overrides/

 

repair permission's

 

 

next need is new version of LaptopDisplay.kext , i will post when i have it working and tested

 

thanks

Thank you very much np_ for your work!

 

I have two questions:

 

you should have now folder with name "DisplayVendorID-"(ur vendor 4 chars hex ) and file inside called "DisplayProductID-(your display product hex 4 char ) in same place "DisplayUtility.app" is located

 

copy that folder with file inside to location /System/Library/Displays/Overrides/

 

repair permission's

Both the folder created by DisplayUtility and the file within it seem to have the exact same permissions of the folders and files contained in

 

/System/Library/Displays/Overrides

 

namely:

 

Folder is drwxr-xr-x, owner root wheel

File is -rw-r--r--, owner root wheel

 

Is there still need to repair permissions? And, in this case, what are the correct commands?

 

next need is new version of LaptopDisplay.kext , i will post when i have it working and tested

 

With the newly created DisplayVendorID, the old version of LaptopDisplay shoud work or we must wait for the new one?

 

Thanks again :)

Hi np_,

 

Maybe there is somthing wrong in the DisplayUtility.

Nope! np_ has it right. Just take a look inside some DisplayVendorID-610 files and look at the EDID information on some of Apple's monitors, like the

DisplayProductID-9d02, for instance...

The question was if the ID is correct or not on the folder name - the DisplayVendorID.

 

The digits are transposed on my output as well. Maybe they are supposed to be. But then it is curious why they are not transposed on the DisplayProductID. We are just lasking np_ to confirm that this is all correct.
