[Guide] Triple or quad monitors with two graphic cards

Recommended Posts

thanks to macgirl for the hints :P

 

now I have three monitors connected with a nvidia 7300gt (gainward) and a 7300gs(pny).

all resoutions QE/CI and rotation - all supported! tried it also with a fourth display - and it worked !

even sleep (except proper shutdown after wake up)

first of all I had no success using nvinject. I followed this instructions for creating a string for two identic cards

 

http://forum.insanelymac.com/index.php?showtopic=101121

 

downloaded the plists from this thread http://forum.netkas.org/index.php/topic,55.0.html

 

first I couldn´t get the device paths, because the 7300gs appeared only as "monitor" in systemprofiler. so I pluggged in only one card and used gfxutil.

 

having all the neccesary details I merged the edited plists as described to one plist and created the hex file. pasted it as a string in com.apple.boot.plist .......et voila !! :P

first I plugged only the GS card into the second pci-e slot and looked for the device path using gfxutil: ./gfxutil -f display

and received PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x0) did the same with the GT only in first slot and received PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0).

 

pasted each in the first "key" line of the according plists that I attached. after that I merged the plists using textedit to one plist file.

 

using this command with gfxutil I created the hexfile: ./gfxutil -i xml -o hex merged.plist out.hex

 

opened the out.hex with textedit,copied and pasted the text as a string in apple.boot.com.plist.

 

repaired permissions with diskutil and removed Extensions.mkext and kextcache

 

sudo rm -rf /System/Library/Extensions.mkext

sudo kextcache -k /System/Library/Extensions

 

that´s it :(

 

P.S.: @ ricren - my whole specs are in my sig

@amantheboy08 - try it.looks good! did you check the device paths?

 

@Guedes Jr - if the x1900 is supported and you could get a dump or a plist file it should work.

Will this work with an ATI card?

 

I have 2 ATI 2600 Pro's

 

if the card is supported it should - just try :D

Well what i was wondering is whatever process i am going to have to attempt is this even compatible with ATI cards? I saw that you yourself was running nvidia and i didn't want to break anything.

 

If this is easily reversible I'm all for giving it ago, but if it's a futile idea i wanted to know from the start :D

 

Thanks

I can´tgive you a warranty that it works on your system.if you don´t want to break your system you shouldn´t try it. also I can´t understand you guys......if you want to be on the safe side: why don´t you buy a mac?

 

or just setup a pretty safe system: install a small partition with another leo on it (10 gigs) backup your main install with a clone tool. put all your important data on a third partition - here you go!

 

all the development here came from trial and error :P

HI,

 

I try w 2 geforce, one 8800GT and 7300 GS

 

if i put only only one string, suystem boot up fine, but give me only dial display, second card is shoew PCI device but no monitor signal.

 

If i put efi striing w 2 vga cards, system freeze after logwindows start !!!????

 

if i use one vga w efi string and another w inject, same, system freze....

 

BTW: i make plist used one vga at time.....

 

any idea?

 

thx

as far as I understand you (difficult language):

 

you can´t use efi strings for gfx and nvinject the same time - you have to delete nvinject :)

Well, is not that you "can't" use them both, but Nvinject "kills" the effect of gfx string, but only in the Graphics card, gfx string could have other device properties as Sound or Ethernet (Time Machine fix) or maybe other.

 

So if you have gfx string with certain properties and NVinject with another the NVinject's will prevail.

Hello, I have two same cards Sapphire ATI HD 3650 512mb. ... I want to have working GFX string because I like to have picture on 3 same monitors. Two lcds on one card working flawlessly with ATI installer from lastExile ( http://forum.insanelymac.com/index.php?showtopic=107526 )..

When I put second ATI to my second PCIE slot, system profiler will show the card correctly! Everything looks fine, but it is not working

When I switch in bios to PEG2, everything is working too, but on the second card in second slot (logically). So the system see booth cards correctly.

 

Problem is that I cannot try GFX strings, because, after deleting Natit.kext, I didn't get low resolution (as described in aquamac how to http://aquamac.proboards106.com/index.cgi?...=569&page=1 ) - but I get screwed picture, so screen is unusable. System boots up correctly, everything is working, but picture in login screen is screwed;(

 

All I can do is boot with -x set up boot plist file with hex string, but after reboot is picture same like with original boot plist.

So any advices? ...

I made manually, boot plist - setting up plist file and generating hex with gfxutil (paste into boot plist)

 

My plist look like this

for me the pci root of the second card looks a little bit weird : 0x1c .....shouldn´t it be just an other number than 1? like 0x2 or 0x3?

 

did you check the pci roots with plugging in only one card in the according slot?

hello, thanks for the reply

 

yes, 0x1c looks little bit weird;) but it is what gfxutil said. i tried both cards in both slots separately (one in first PCIE, and one is second PCIE).

 

but problem I have is before this step - if I just leave only one ATI card in computer, delete natit.kext and then reboot (original boot plist). it is not possible to login to system, because after grey apple (correctly shown), login screen is messed up.
