sudo lspci -nnvd 0x1002: | grep -B2 Subsystem

The problem is i have only 3 output on mini display port with active display port out, That's probably because frame buffer duckweed

I use Chimera boot loader

 

bdmesg

System information show only 4 connector but only 3 is working, one of the connectors go only with detect display

On boot i type aticonfig=bulrushes but its loading default framebuffer Duckweed from chimera boot loader.

I don't no what to do!!What is wrong! I really need 6 output

[Frankenst1]

Any updates so far? I'm struggling as well to get 6 outputs to work with a 6870 Eyefinity 6 (1002:6738).

So "Bulrushes" should be the correct framebuffer instead of "Duckweed" for 6 displayports (00 04) on a 6870.

 

However running any of the following options and their combinations result in a grey screen after the OS X load spinning wheel:

-GraphicsEnabler=No

-PCIRootUID=1

-AtiConfig=Bulrushes

I'm having the same issue here, but I only need to get 3 monitors to work. Did you guys get the third to work ?

[Frankenst1]

@baguazao: Nope, if you only need to get 3 outputs to work, I suggest you get a regular 6870; works out of the box for me with 3 monitors.

What type of MDP>DVI convertors are you using? and where do you have each monitor plugged in? 1MDP,1DVI,1HDMI?

 

I have an MSI 6870 and can only get 2 working at a time

[Frankenst1]

What type of MDP>DVI convertors are you using?

 

I'm using XFX Adapter Mini-Displayport to DVI (Active, Single-Link). The active adapters from Club 3D did not work.

 

and where do you have each monitor plugged in? 1MDP,1DVI,1HDMI?

 

Yes,1xDVI (upper one),1xHDMI,1xMDP

 

I have an MSI 6870 and can only get 2 working at a time

 

 

Seems like having the right active MDP->DVI adapters is crucial. Like I mentioned above, Club 3D adapters (albeit being "active") did not work, the ones from XFX did.
