Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

OK, for the time being, I personally wouldn't worry about the (WW) Direct Rendering Disabled message, because as far as I know, this just means that performance will suffer because there's no DRI.
Y'know, this *could* be why you said you thought one card seemsd slower than the other.
Also on that subject, I don't recall you having an Extensions section in your file. I believe with ATI driver(s) if you want DRI you need an Extensions section in which DRI is enabled. I can't recall the Exact format, but its something like: Section "Extensions"
Option "DRI" "Enable"
Mode 0666
EndSection
.. but don't directly quote me on this, verify the syntax first..
OK, I'm gonna go and look at the file you posted again, and compare it to the other (WW) messages you just posted, and be back in a few moments...
OK, the device at PCI 5:4 is the onboard VGA device. That's the one you want to label and name, including the BusID, but don't use.
The cards you want to use in the slots however, will be the ones in 13:4 and 12:7
one of which you DO have specified in the file, but the other you don't.
Going back a few steps, have you checked into the IRQ sharing? If you can't come up with a way of making sure that the cards aren't sharing an IRQ, perhaps noting which pairs of slots share IRQ's and moving the cards so that they are in slots that NEVER can share IRQ's..
The cards are in slots that do not share. For example I think 1 card is in slot 4 and the other in 5 and the sharing is 3-4 and 5-6.
Nothing has changed since last post... 2 monitors working from the 1 card and the other 2 are getting getting powered up by the card but the screens remain blank? I know the other 2 are working because on startup they show the boot process then when xorg starts the other 2 are configured first in the conf file and they work but then the first 2 go black.
OK, I can go with that-- it makes sense. I had been basing my opinion that 5:4 was indicated in the log as being "the primary device" but apparently that did not mean it was the "onboard device"..
So.. Humm.. I'm just re-reading the thread here to see what's what.

Again thanks for your help...
No problem, I'd like to see this thru and see it work.
May I rephrase/chop this quote up to clarify??
>> When you first turn on the machine,
A) Do all 4 screens activate electrically (power ON)?
B) Do you get the BIOS data and/or boot logo screen on all 4 of them? or just on 2 of them?
C) Next, when Linux is loading, do you get the text console scrolling up 2 screens, or all 4?
D) When X starts (notwithstanding my B and C questions) do 2 of the screens go black? If so, do they remain powered up and go black, or do they TURN OFF and go black?
The machine powers up on 5:4 x2 (xorg.conf not yet involved)
Linux loads on 12:7 x2 (xorg.conf still not involved)
X starts: 12:7 x2 (xorg.conf in use now)
OK.. *thinking cap is on*
Will you post the entire xorg.conf file, as it is right now? Let's have a look at the virtual locations of the screens. I'm not discouraged here; it's a good sign that the black monitors are still powered ON. Maybe their images are simply not being "put onto them".

Wait my bad... Linux loads on 5:4 as well. I get the login screen on 12:7

OK.. It's a half-decent README page.. Should i be looking at anything particular there? What I AM wondering, now that I have seen it, is whether or not the driver (or whatever) is simply saying to itself "OK, I have activated one card, two screens, and that's all I think I need to do.." ?
Other thoughts:
Option "MonitorLayout" "blah, blah"
(maybe to force/simulate detection?)
this one's interesting, but maybe irrelevant:
Option "NoMergedXinerama" "boolean"
---Your META modes are commented out.. How come? I think they would help. They might be necessary.
--- Add Option "Xinerama" "on" to each DEVICE section. May not help, but won't hurt.
---- Are your monitors CRT's ?? Or flat panels? If not CRT's, change the CRT- in the metamodes to <whatever monitor type>, if using the metamodes.
Could be that without the 'Xinerama' option in all the device sections, the driver doesn't knwo waht to do WRT Xinerama. Maybe this is why the other 2 screens are blank.
I know there's lots of 'maybe's' and 'could be's' but well, I say it'll work eventually.. Maybe soon OOps, another maybe.. :/
FWIW, I have never used Xinerama or TwinView without MetaModes. I kinda thought they were necessary. Mind you, I am using nVidia too, though I don't think that detail would be different.
