Natit for Nvidia with dual display

161 posts in this topic

Recommended Posts

Hi,

 

I have a P4 running 10.5.5 with the Munky Method and all I had to do was to edit the NVCAP value in Natit to

 

04000000 00000100 02000000 00000000 00000000

 

And I have dual displays working with QE/CI and rotation enabled.

 

Thanks!!!

Dual Display is now working with my 7300GS card!!!!

 

It is a bit of a nightmare to find all the info you need to make this happen and it took me a while so i thought i would post up how i did it.

 

Ok so basically after trying every option i could I found a post with a pre-made NVCAP string for the 7300GS and I grabbed a copy of Natit Dual 0.2.

 

Search in google and a download will be there somewhere. I opened up the Natit Kext by clicking on show package contents and edited the Info.Plist with Text editor and copied this string in place of the existing NVCAP value: BAAAAAAACQAOAAAAAAAABwAAAAA= then saved and dropped the Kext into Kexthelper. Entered my password and let Kexthelper do its thing. It repairs permissions etc for you so no Terminal stuff if your a noob.

 

Re-booted, adjusted the resolutions and cailbrated each monitor. DONE!

 

The NVCAP string in the Info.Plist will look something like this:

 

<key>NVCAP</key>

<data>

BAAAAAAACQAOAAAAAAAABwAAAAA=

</data>

 

If you dont change the NVCAP string it wont work trust me! The string is specific to 7300GS only so dont try it with another card it could cause major problems.

 

Out of interest this is the NVCAP string for 7300GT

 

<key>NVCAP</key>

<data>

BAAAAAAAAwAMAAAAAAAABwAAAAA=

</data>

 

Currently have it working with a 22" Samsung and a 19" Philips but im now off to buy a 2nd 22" Samsung! Will be great for Logic Audio thats for sure.

 

I hope this helps someone who was in the same boat as me. If you have a different Graphics card just try searching for the NVCAP in google.

Happy dual screening :D

PS: If you muck it all up and it wont boot try -X -V at bootloader and boot into safe mode, that way you can have another go.

 

I´ve been running two 7300gs video cards in my hack (possible to run 4 monitors) for months now using an Nvinject.kext I edited a bit. All is enabled, got the kext uploaded to a thread in hardware/graphics cards if you search for my threads.

 

Check out the video

I think in order to use a Nvidia card for Physx, you need to install the graphics Forceware drivers too. So in short, you cant mix them unfortunately. I too also want to do this because I have a spare 640MB 8800GTS lying around.

I thought I'd followed this correctly but am getting:

 

"System extension cannot be used... Natit.kext was installed improperly.."

I NEED TO USE DVI PORT

I used all known ways;

1. GFX String way on aquamac site seem {censored} cause you need leopard to write right gfx string to use on snow. Why do i need to install 2 operating systems to use this card.

2. Graphics Enabler works on only vga and and no qe/cl.

Then i use the DSDT fix in DSDT se and now on System profiler, everything seems ok, but i still cant use dvi port. I can open iMovie but nothing written about Quartz Extreme support on System Profiler..

When i try to see Quartz Extreme status on OsX86 Tools, i see an error like this:

”Can’t make "The domain/default pair of (com.apple.windowserver, QuartzGLEnabled) does not exist" into type boolean. (-1700)”

Theres 3 output on graphic card: VGA, DVI, HDMI..

I can only use VGA

It seems that a number of Nvidia users have had problems running dual displays with the newer versions of Natit. Although I did not try all of them, I had problems too, my second display was sideways and without the mouse cursor.

 

Natit v0.02 works for dual displays on many Nvidia systems and it is what I am using. I am also re-posting Natit v0.01, which should work for VGA/DVI Nvidia cards, for people who have problems with v0.02 and want to try something else.

 

However, v0.01 and v0.02 are very similiar, v0.02 merely adds the "@0,NVMT" key and value. For more information on these key-values pairs and how these dual display versions of Natit for Nvidia was developed, see these threads:

 

http://forum.insanelymac.com/index.php?showtopic=31833

http://forum.insanelymac.com/index.php?showtopic=32536

 

Now for people who have problems, here are two general suggestions:

 

A. Make sure you are using a clean install of 10.4.8. People who upgrade to 10.4.8 (or mess with the Nvidia kexts) often have problems.

 

B. Make sure you follow these instructions (specifically removing the .kextcache and .mkext) when installing Natit (again, these instructions and the original idea of Natit are credited to Omni).

 

(1) Put the Natit kext in your /System/Library/Extensions/ folder. 

(2) Correct the file premissions: 

sudo chown -R root:wheel Natit.kext; sudo chmod -R 755 Natit.kext 

(3) Remove the cached and packed extensions: 

sudo rm -f /System/Library/Extensions.mkext /System/Library/Extensions.kextcache 

(4) Reboot.

 

UPDATE: Natit for dual display works with Leopard (10.5) too.
