quad monitors (dual pci-x)

[traverse]

(Correction: PCI-express and not pci-x)

Hello,

I'm trying to get a quad monitor setup working on a new machine. I can get two monitors working on the primary video card, but the other two monitors remain blank. Here is the relevant information:

- Tyan S2895 A2NRF Thunder K8WE Motherboard (amd64)
- Nvidia kernel module version 8178
- 64-bit Vanilla Kernel 2.6.15

- lspci | grep VGA:
02:00.0 VGA compatible controller: nVidia Corporation NV41GL [Quadro FX 1400] (rev a2)
81:00.0 VGA compatible controller: nVidia Corporation NV41GL [Quadro FX 1400] (rev a2)

- xorg.conf: (relevant sections)

I've tried altering the "UseInt10Module" and "Xinerama" options with to no avail. The Xorg log files keep reporting,

(II) Primary Device is: PCI 02:00:0
(WW) NVIDIA: No matching Device section for instance (BusID PCI:129:0:0) found
(--) Chipset NVIDIA GPU found

Trying to set the "nvidia1" BusID to "PCI:129:0:0" results in either,
- the X server getting a SIGINT before any log information is generated, or
- the exact same error message,

Depending on a combination of options that I haven't quite figured out.

Any help would be much appreciated. Thanks in advance!

Actually... *smacks head*

I've almost got it working now. I'll post the resolved xorg.conf file soon. I spend a whole day working on it, and I finally get it (almost) working five minutes *after* posting on the forums.

As promised, here is my working X configuration for 2x2 monitors. The only slightly non-ideal part is that when an application is maximized, it spreads across 2 whole monitors (instead of just one, which happened to be the case when I only had two monitors working).

The SIGINT error that I was getting was from having two "UseInt10Module" options set. Should have looked more closely at the log files - I didn't think one was really being generated earlier. My bad!
