Hi,

I am having the dual monitor DVI issue right now with my brand new CostoMac. I found this tread, read it over and over (including the insanelymac links) but I gotta say that I am confused and don't know what to do. Personalities, Kexts, editing, gabba, I dont even know where to start.

I am all new to this. Can someone please post a small tutorial (even in bullet points) of how to get dual DVI monitors to work with the 6870 in steps.

Forgive the N00bness!

Thanks

in your boot.plist add:

<key>AtiConfig</key>
<string>Gibba</string>
<key>AtiPorts</key>
<string>5</string>
<key>GraphicsEnabler</key> 
<string>yes</string>

and then replace (after taking a backup) your existing ATI6000Controller.kext with the one you can download (after registering) on http://www.insanelymac.com/forum/index. ... try1795360

Then restart everything and bingo, all your ports should be working.

Thanks Rumey.

That's pretty straight forward and simple enough.
I shall try it when I get home tonight.

Cheers.

It doesnt work for me.

1 - The first time was my fault because I hadnt changed Gibba to Gabba. When I rebooted, The screen just froze on the Apple loading logo with the spinning grey circle at the bottom.
(Surprizingly enough, this was showing on both monitors). I coulnt boot into Lion, so I was forced to reinstall the entire OS.

2 - The second time, I changed to "Gabba", placed billdlv81' "ATI6000Controller.kext" in the extensions folder (just simple drag and drop). double checked all the steps mutliple times. I restart, I get stucked on the Apple logo again with the spining grey circle bellow it, On both monitors.

I don't know what I am doing wrong. I guess I have to reinstall LION again.


Someone help?

Hi, as someone else said it should be 'Gibba' not 'Gabba'.

I'll see that I post my boot.plist this evening here (if I don't forget, I have a lot of work to do )

Gibba?

Well in that case I did it right the first time, and my computer still froze on the apple logo on start up.

Here is what I did. Maybe you can tell me if did something wrong.

- I downloaded billdlv81' "ATI6000Controller.kext from here http://www.insanelymac.com/forum/index.php?showtopic=275546&st=0&gopid=1795360&#entry1795360
- I went to /Library/Preferences/SystemConfiguration and edited com.apple.Boot.plist to look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Kernel Flags</key>
	<string></string>
	<key>AtiConfig</key>
	<string>Gibba</string>
	<key>AtiPorts</key>
	<string>5</string>
	<key>GraphicsEnabler</key> 
	<string>yes</string>
</dict>
</plist>

Note: When I first got to my com.apple.Boot.plist, It was locked to prevent me from editing it. So I created, edited a duplicate, and saved it to my desktop as a .txt and then manual changed it to .plist. Then I went on to delete the previously existing com.apple.Boot.plist and replacing it with my new one.

- I went to /System/Library, grabbed a copy of the existing ATI6000Controller.kext to my desktop, deleted it from the folder, and then replaced it with the the one I had downloaded .

- I plug only the 2 DVI-D cables in the 6870 and restart the system.
- The system gets stuck on the apple logo. can't fully boot into LION.

Note: I have 10.7.3 and I am booting from my SSD using Chimera.

Can anyone tell me if I missed a step? or is my system just ****ed.

Thanks

I'm in 10.7.2 and also start from SSD.
Have you tried to run kextutility afterwards? That sometimes cleans up stuff.

I also run Onyx when faced with problems to clear caches etc.

I'll see that later today I'll post my boot.plist, it is a bit longer than yours.

ok here is my info:

I'm using the org.chameleon.Boot.plist file in /Extra folder.
It's content is:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Kernel</key>
	<string>mach_kernel</string>
	<key>Kernel Flags</key>
	<string>npci=0x2000 darkwake=0 AtiConfig=Gibba AtiPorts=5</string>
	<key>GraphicsEnabler</key>
	<string>Yes</string>
	<key>Quiet Boot</key>
	<string>Yes</string>
	<key>Legacy Logo</key>
	<string>No</string>
	<key>EthernetBuiltIn</key>
	<string>Yes</string>
	<key>Graphics Mode</key>
	<string>2560x1440x32@60</string>
	<key>UseKernelCache</key>
	<string>Yes</string>
</dict>
</plist>

For you the most important are the Kernel Flags and GraphicsEnabler.

The com.apple.Boot.plist is still:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Boot Logo</key>
	<string>\System\Library\CoreServices\BootLogo.png</string>
	<key>Kernel Flags</key>
	<string></string>
</dict>
</plist>

I hope this helps

- kextutility
- Onyx

As you might have noticed, I am a total noob at OSX "hacking".

I just checked out those 2 programs you mentioned.

Question: Do I use Kextutility to install the Kext file I downloaded from Insanelymac instead of just dropping it into /System/Library?

Onyx seems straight forward enough. I will surely use it.
