What should I do after I download the laptodisplay.kext file onto my dexktop

Carlos Pombo · October 3, 2007

My Laptop display fails to assume and work with any display calibration or color icc profile.

I'm able to calibrate and output a profile using Spyder2 calibration tool. Happens that none of available profiles works. Changing profiles as no visual changes in display.

It is useless for photographic editing.

Using ATIRadeon9700 and koverge patch I can get CI & QE working, even Q2E with some occasional display refreshment square loses.

Who can help me suggesting what to change or look for? Seems to be something related with the way Graphics establish connection with Laptop display.

Hi, first of all: i'm new here and trying to understand what it's all about.

I have a problem with my medion laptop (md95800) with Intel GMA900 GFX.

After the installation the pc boots with an external display, but not with the internal.

After that i've followed the LaptopDisplay steps, which didn't do anything (maybe i did something wrong??).

Then i've tryed typing -F platform=X86PC at the boot, which kinda worked, and got me onto the desktop without backlight (backlight falls out after the blue loading screen).

Same thing happens with the paperclip trick.

So, my backlight doesn't light up on the desktop.

Does anyone know how to fix this?

Hey, I'm new to all this Mac OS.. but i'm eager to learn..

I have a problem with my laptop display.. it works fine with VMWARE but when i boot it native it gets stuck in the grey screen.. but i know the system boots, cause i can shut it down with the key shortcuts..

I wonder if your display driver will work.. but i'm having a bit of trouble figuring out how to use it.. can you give me a help? i'd love to try this out to c if it is the solution to my problem

Btw my laptop is equiped with a ATI Radeon Express 1150

Cheers..

manmal · October 26, 2007

can i have mirror with this?

SuBDivisions · November 6, 2007

Ok i have a sony vaio laptop with a Geforce 6200 Go in it and i get the External Display working Perfectly with all that QI crapola whatever it is working, full accelerations.. using that Geforce Installer pack i found in the forums... But I can not get the laptop display to work at all using the laptipdisplay.kext and NvidiaEFI. I even tried the paperclip thingy to no avail..

I get the white screen, plug in my enternal dell 20" monitor and it works perfectly..

Any further on this? Can i help in any way?

zillion42 · November 13, 2007

Hi,

I read the whole thread (took a night and a morning)... I feel kind of for reading eveyones detailed error descriptions and trying to extract some usefullness for my own problem...

First of all a couple of questions:

1. I read a couple of times to remove all AppleDrivers... Whats their names and where are they ?

2. How can I make an ioreg while booted with a white fading, strange colour displaying internal LCD ?

As far as I can think, I tried nearly everything mentioned here except the removing of AppleDrivers and putting the EDID inside Natit's Info.plist. I couldn't find where I should put it inside the Natit's Info.plist, there was no vendor child and no EDID,LVDS silbling to find ?

Instead I put the full EDID data inside Titans Info.plist under EDID0 and EDID1. Doing that is quite interesting because that's how I found out that, first my EDID data seems to be correct and second that my internal is EDID1, whereas my external is EDID0. When I put it for EDID0 it set my external monitor to 1920x1200 and called it ColorLCD, when I put it for EDID1 it tries it for my internal I guess, but I only see white fading. I have a toshiba internal display with 1920x1200... MonInfo gives me "TOSHIBA Internal Panel" and "DisplayVendorID-51f3" results from DisplayUtility. I also put my EDID block into the "DisplayProductID-508d" from DisplayUtility.

Anyway, none of it got my internal Toshiba Panel working. I keep on seeing the strangest white fading combined with black and blue blocks burning out previous contrasts... It's nearly like a screensaver, or a scare: "Ohh god, I ****** my Laptop Display !!", anyway it doesn't work...

If anyone can give me instructions on how to make ioreg without seeing anything and which the apple drivers are, I'd be helped a little...

thanks.

Edit: Added internal Toshiba Panel EDID data from MonInfo...

-Q- Master · November 20, 2007

How did you make your card work ? I have a GeForce Go 7300 and I installed Natit but its not working should I install Laptop Display ?

Why so many similar packages ? I'm a bit confused.

Oh my god!!! The long standing problem is gone!!!!!!! What I did was load BOTH Natit Uni 1.0 & latest NVidiaEFI. Thanks alot np_ !!!!!

HackBook Pro · November 21, 2007

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" !

So what exactly does this do? Will it enable my laptop's backlight (so I can change the brightness) in OS X?

P.S. Will this even work w/ my laptop (stats in sig)?

captainLoknar · November 28, 2007

Good effort, but..

ok, I tried this kext at my own risk and I couldnt boot anymore. Yes, I'm no expert.

Description:

Acer Aspire 5540 (ATI X1300)

-I installed 10.4.9 with X1300 driver

-The LCD panel did not work, then I always used external LCD and tried many drivers (not callisto)

-upgraded to 10.4.10 and 10.4.11

-I saw this thread and I copied the laptopdisplay kext. After this I could not boot or repair the video driver - it always crashed before the gray apple. (I dont know how to prevent the kext from loading. Its probably because I didnt have a callisto driver.. but how should I have known?

Now im using Callisto and I can use Panel or External but not both, and retricted to 1024x resolution (native of my panel should be 1200x800)

Well this is my story!

keplenk · December 8, 2007

hi all,

Will this step work with Leopard 10.5.1? I can see that this thread started a long time ago (even before Leopard was released), will this work?

Thank you very much.

EDIT: What I meant about "will this work?" is the Laptopdisplay.kext made by np_ (by the way, thanks and great work!) to work with Leopard =)

I read almost all of the previous posts and I must say I was confused (Im a noob) =(

I have a working Natit.kext from Paulicat (I have GMAX3100) but When I install it, I have to install Switchresx or DisplayConfigX just to get 1280x800 resolution.

I was hoping that if I use a modified Natit.kext with my EDID inside, I dont have to intsall SwitchResX or DisplayConfigX anymore.

I got my EDID information using Windows OS and DumpEDID. But I dont know where to start.

I dont know if the LaptopDisplay.kext by np_ is still needed or not. If not, where do I put the EDID in Natit?

I guess what im trying to say, If this will work in Leopard, what is the easiest step by step guide.

THank you very much.

J. Weggemans · December 16, 2007

I have a IBM T40 with a Ati Mobility Radeon 7500 32MB.

I've tried several install cd's.

ToH RC2 - Install disc boots but booting ends just before going into graphic install mode.

JaS 10.4.9 - Installation succeeded, but system halts with a black screen, in safe mode white striped screen.

Will this laptop kext do the trick for me?

What do I need to do to install it?

What will I need to do to install ToH RC2? Prepatch the DVD?

Thanks!

pop_aka_kiki · December 26, 2007

This project appears to have been quiet for some time. np_ indicated his updates would appear over at the macvidia forum, however the domain is no longer valid and therefor the forum is unreachable.

does anyone have any information about laptopdisplay.kext or the macvidia team?

s3mt3x · April 23, 2008

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

np_

i've done that above..

But it doesn't get my vga info :

DisplayVendorId : None

DisplayProductId : None

So, on my folder doesn't have any EDID at all

I;ve try many ways, with natit, the gmax3100 provide by iATKOS DVD and Kaly, it doesn't work at all

Always got bad video, restarting on login ,..crash on normal mode etc..:censored2:

My Laptop : Toshiba Portege M600-E311

Intel GMAX3100 <--- Must login with -x option, i never can get my normal mode boot

Intel HDA Soundcard <--Once i get my normal boot, i think i can handle it with taruga's stuff

Ethernet Realtek 8169 <-- OTB

Wifi Intel Wireless 3945 <--Still wating for the package done..

Thx,

Adnan Khan · June 6, 2008

Wow this seems to be interesting, i'm going to try it later and put my success or failure story :thumbsup_anim:

ADoNuT333 · June 10, 2008

This didn't work for me. It didn't even register.

fatfatwolf · June 11, 2008

under "any" i do mean any laptop ( old or new ati or nvidia or whatever else video card )

Even including those Mobility Radeon X1300s? I thought ppl were saying that LVDS is not supported within X1300 driver, so there's no hope to get it running?

RaFaeL_Rj · July 13, 2008

Where can I get the driver to make my GMA965 X3100 work properly?

Thanks in advance!

mrbonkers · July 16, 2008

isnt working for me, booted in verbose and it shows "could not alloc class "IOPanelDevice""
