[SOLVED] Asus ROG laptops with Kepler cards not detecting DP-2 connected LCD display

asus gtx 770m G750

Best Answer AREOS, 20 March 2014 - 04:46 PM

Hi,
@AREOS: I have attached 2 ioreg files in the zip as my laptop acts slightly differently with the NVidia drivers.

When it starts from the vga monitor the internal lcd is not detected. Only the monitor. Thats the ioreg monitor only.
I can then go to displays>detect displays and then it finds the internal lcd also. Thats the ioreg monitor and lcd.

Before on the mac driver the monitor was always found first and then the lcd fired up a couple of seconds later before login.

Hope that helps...


OK is interesting, your eDP port is detected on Display-B, but this maybe caused by the wrong NVCAP info, I check the iMac 13,2 and 14,2 and this machines had only 3 ports A,B,C maybe is because they don't use the internal port as they use eDP too for the display, I have one EFI string to test, this will change the NVCAP to inject the iMacs, and also injects the correct connector type, and display cfg. In my testing I can actually boot with all this info injected and working, but only using Nvidia Web Drivers, I suspect this is caused by my internal connector is LVDS, and the apple drivers doesn't like it. So try this EFI string only using Nvidia Web drivers.

Please report back with IOReg saves to see if the info is injected correctly.

This is the EFI string, and good luck.

With an correct upsetted EFI string, as I have written before. I have gotten an used L702x 3d by chance and my method is working on it like a charme. I have found nothing about an as internal recognized display on this device. My device is working in this way, very well.  Yes it is only Fermi, I know. I have not removed any of the OSX gfx related kexts. The L702x has the IGPU in his DSDT. The only part of the IGPU, that is showing up after boot is, the full registered AppleIntelMEIDriver without infecting anything. As I have also told before, I am not able to test my method on a device with a kepler card, because of having it on repair after bricking it.

 

In any way, I am trying to get my devices in a vanilla way up by staying way from any kind of Distros, MyHack or other automated generating installer tools. I make the installer manually in a similar way like this one, which is described in the following link: http://www.insanelym...-for-mavericks/

 

I always try to use an as near as possible my hardware matching SMBios of an real AppleDevice and place only the fakesmc and nullcpupowermanagement kexts - on laptop also ps2driver - in S/L/E of the installer. After successful hd install, I install these kexts with terminal, by booting once more from the usb installer, on the hd install and repair permissons too. For getting rid of the root device error sometimes an install of genericusbxhc.kext in S/L/E of usbinstaller and copying it also to the hd install with the other before mentioned kexts is usefull. For gfx related problemes I tempeorary remove the to the hardware of the device related kexts from the usb installer.

 

After successful login to the hdinstall I install, if the device has an as common working known ethernet nic the neccessary plugin in ionetworkingfamiliy.kext or edit an related info.plist (for example the marvell one) or inject it with a legacy.kext. Then I always try to get the gfx card as good as possible working and get an unkown display recognized by doing an forced display EDID. After that I try to generate a proper working DSDT, try to get the audio working with an patched applehda.kext, if there is one, generate an SSDT.aml, patch the Powermanagement and try to get it working by removing the nullcpupowermanagement.kext. If there are things left not got working by DSDT edit, one can try to install the proper especiai kext to get it working. In any case one can then see, if this kext is infecting other before working things.

 

Have fun.

That is exactly my method!!!!!!!!!!!

Hi,

my Asus has the IGPU physically disconnected so i dont think this method is going to help.

I think I've got a clue that will lead us to know what happen with this issue. Based on a tip from @Styrian, I've extracted the original NVCAP from the VBIOS rom, and stored the string in a pendrive. Then I booted (without NVDAResman.kext, of course) with GraphicsEnabler=Yes, started IORegExplorer and noticed the NVCAP is different than the one extracted from rom. More, I booted with graphicsEnabler=NO, started IORegExplorer and noticed that NVCAP is different than the other two.
So, three different NVCAP strings in three different situations.
Then, I tought that the correct NVCAP must be the one from rom and I injected it in chameleon with the method described above in other post. Chameleon saw the string and injected it, but nothing happened. Now, that is extremely curious.
We need to patch NVDAResman.kext to match that NVCAP?? Dumb saying...

What EFI string? I can´t find it

 

On other words, here is a list of courious things I´ve discovered trying stuff:

 

A - I reached to boot with NVDAResman.kext, but then I discovered that it was no info.plist into the kext. As you can see in attached image nor 1. Maybe OSX just bypasses the kext when there´s no info.plist file inside OR maybe we could modify the info.plist to remove strings that are bothering.

 

B - In the systemInfo.app that I downloaded somewhere, there is some information about text related with the graphics card that I never noticed before. See attached Image nor 2

 

C - I can´t find a way to inject the NVCAP without using GraphicsEnabler=Yes

Ok. Tried. Still can't boot with nvdaresman. However, the EFI make the graphics card name and its vram shows correctly without nvdaresman

 

Maybe it´s time for praying for help to Ermac or RampageDev. Or both. What do you think?

Is your Kepler card showing up on NVDA display-A? Is there in systemprofiler the monitor symbol for an internal laptop display?

 

I´ll try at the weekend some things on Fermi. If I get my ideas working, I´ll port them for you in an EFI-string to try.

 

If you have a working DSDT.aml and SSDT.aml you could try with Enoch bootloader 2269 in energy options to set all tables Dropxxx=yes.

 

Can you please upload an ouputfile of IORegestryExplorer, vers. 2...., after booting with my EFI-String and GE=No?

 

Have fun.

Injecting the NVCAP with chameleon is extra-easy as:

 

<key>GraphicsEnabler</key>

<string>Yes</string>

<key>NVCAP_gfxid</key>

<string>xxxxxxxxxxxxxxxxx</string>

 

But ....What is indeed the NVCAP? Some sort of configuration about the output connectors of the graphics card??

 

Anyway

@Styrian, the NVCAP extracted from my VBIOS rom is 0400000000000100020000000000000700000000

 

What does it means?

The NVCAP string can separated 20 hexadecimal parts, like 0x04, 0x00,...... The first part 0x04 is 0100 in binary format, means single video card slot. The 7th part 0x01 is the primary card ports and the 9th part 0x02 is the secondary card ports. The 7th part 0x01 is 0001 and the the 9th part is 0010, each bit means one port, 0 is off, 1 is on. According the information offered before, the 1st bit mans TV port, the 2nd bit means HDMI port, the 3rd bit means VGA port, the 4th bit means DP port. So the primary ports 7th part 0x01 means the DP port is on, the secondary ports 9th part 0x02 means the VGA port is on.

 

According the @Styrian's opinion, the NVCAP of mobile kepler card can do nothing on OSX, so NVCAP is useless for solving the problem.

@vislo4

 

Thanks for the exellent information.

 

Apple is using for the iMacs 13,1/13,2/14,2 these same values for NVCAP: 0500 0000 0000 0100 0600 0000 0000 000f 0000 0000

 

The MBP 9,1 and 10,1 have these values for NVCAP:                                   0501 0000 0000 0100 0600 0000 0000 000f 0000 0000

 

The MBP 7,1 with only Fermi gfx has these values for NVCAP:                     0501 0000 0000 0100 0600 0000 0000 000e 0000 0000

 

Does anybody know the meaning of the with colors marked digits?

 

In any case it seems to be important to add @0,fboffset data 00000200 in an EFI String for internal laptop display, to get it dedected as internal on port 0 by OSX.

 

A good source for getting dumps of Apple hardware is this one: http://tdev.me/2010/...hardware-dumps/

 

An Ioreg.rtf file of an iMac 14,2 I have attached below. I have removed parts of the platformUUID, board-ID and SerialNr., which I don´t give away.

 

On the L702x 3D (fully working display EDID) I have added nearly all properties for AAPL00 and @0,...... from Ioreg of MBP 7,1 with the for it set values. This seems to work fine with the GT555m. Display mirroring is also working with the HDMI port. But I know it by myself, Kepler cards are other things.

 

I believe, that we are with an EFI-String not far way from getting the Kepler cards working. But we have to find some of the properties and values, we have to set, perhaps with a healthy mix of properties and values (Laptop and OSX). Even trying to set the Apple NVCAP (or some of it´s values) seems to make sence on mobile devices.

 

Have fun.

@Styrian, I noticed the EFI string you gave me has the NVCAP value of the MBP 9,1 that you wrote in the previous post. Can you make a new EFI string based on the previous one without touching anything but adding the NVCAP from my original VBIOS rom?

By the way, you have a PM

I'm very curious about the different type of Asus G750. I found that Asus G750JX can run OSX Marvericks perfectly. The link below:

http://rog.asus.com/...s-INSTALL-GUIDE

 

I think the difference is the screen, HD 1080p screen works and 3D 120Hz screen doesn't work. Is it right?

I think 3D screen uses the DP port and internal 1080p screen uses the LVDS port, Is it right?

I find that the screen of Asus G55VW-DH71 in United States is LP156WF1-TLB2(LGD02D9). This screen is not 3D screen, the specification of this screen is blow:

The signal category is LVDS.

Don't get mad searching for data. it doesn't matter which type of screen your notebook uses. Is just that if is a 120hz display, uses displayport wich untill know, we can't manage to fire it first to osx recognizes it.

Maybe I'm confused about the conception of screen and display.
I have bought a pcs of second-hand G55VW-DH71 from American Amazon, which has a 1920x1080 screen. I will get the laptop few days later. I have checked the max. refresh rate of the screen is 60Hz. I'm not sure the port is LVDS or not. Do you think the graphics card and screen of my laptop can work on OSX?
ps. I have bought BCM94325HMB wifi+BT4.0 card to change the AR9485WB-EG card. Do you have the AppleHDA.kext for Via vt1802p?

I've made some progress. Well, depends of the point of view indeed. But I've reached the desktop with NVDAResman.kext IN and no extra parameters in org.Chameleon.boot.plist but basics. What happens is that desktop is fully loaded when we think is not. I've just enabled the screen sharing through VNC and once the system seems to be hanged I conneted my ipad to it using the Screens app (vnc connection) and managed to look in IOREGExplorer details. I found then that there are all of the 4 display connectors (being displayA@1, displayB@2, displayC@3 and display D@4) in GFX0. This is very useful because it proofs what I suspected a months ago: that this graphics card has 4 display outputs. The strange thing here is that all of the 4 outputs has display-cfg = ffffffff. I know I can give alternate values for display-cfg 0 and 1 in chameleon, but I wonder if display-cfg 3 and 4 can be indicated too. Maybe chameleon need to add this to its code to adapt itself to new graphics cards.

Curious thing is that you just can't find a display in system information. It just shows no display connected to it. Expected I think, but then I tried to connect the TV to my hackintosh through HDMI nor VGA but it keeps detecting no display. Another curious thing is that under system information there's no info about the graphics card but "NVIDIA chip model 256MB" meaning that we need to modify anything else (like the NVDAResman kext itself or any other) cause NVDAResman is loaded but it keeps not detecting the VRAM and the whole graphics card. Or maybe NVDAResman needs to detect a display to start working. I don´t know yet.

Now question: is there any other utility for Linux similar to IORegExplorer?? That would be amazing because we can then observe the corrects display-cfg data of the 4 outputs.
Below I attached some screenshots starting with my org.chameleon.boot.plist (to let you know that is really clean). Remember that NVDAResman is loaded.

Meaning that my notebook outputs through 4 connectors as:

Connector 0 - (0x282)        DisplayPort-2
Connector 1 - (0x27e)        VGA-0
Conenctor 2 - (0x280)        HDMI-0
Connector 3 - (0x27f, 0x281) DisplayPort-0, DisplayPort-1

I think I almost got it!!!

Guys, I have more information. It seems that some Macbooks Air has their displays connected trough displayport but uses a customized configuration to make them start. We need URGENTLY help from someone who have access to one. The steps to follow are:

1 - Start the MBA with an Ubuntu live Pendrive (or external USB CD drive) on it. Reach the desktop, start a terminal and run:

sudo xrandr --verbose

2 - See if the connection is made through displayport. If you don´t know how to do it, pay attention to the code on the post #59

3 - If it is, run:

sudo xrandr --verbose >> info.txt

4 - Take that file (sure is in home folder) and paste it here to analyze it.

5 - Start OSX, fire IOREGExplorer 2.1 and save a dump to a file. Then paste it here to let us start working with it.

 

 

THING IMPORTANT TO NOTE: all the information in Display0 is extremely important (connector-type, display-cfg) etc

Come on, we can do it!
