Nvidia graphics with onboard HD4000 for three monitors

As I started typing this, I realized there's a FreeBSD Wiki I haven't looked at yet, but I'm running two monitors with an nvidia 9600gt and inherited another monitor. I have onboard HD4000 with a Sandy Bridge motherboard and was wondering if it's possible to use that to run the third monitor.
 
I think it's going to be tricky, the NVidia driver actually replaces a couple of Xorg libraries. Those libraries are also used by the Intel driver but may not be compatible as the driver assumes they're the original Xorg ones.
 
SirDice You might glance over at my other thread where I talk about also inheriting the same nvidia graphics card. So I have two and can't get the second one to drive the third monitor. I just don't remember how to go about setting these up.
 
Yes, I saw that one. I think you need an xorg.conf that defines both cards and three monitors. So you basically create 3 screens and stitch them together with Xinerama. Never tried it myself though.
 
I don't run NVidia or Multi Monitor setups but I recall that xorg.conf entries are the "last read stands"
From the earlier thread:
vgapci0@pci0:1:0:0: class=0x030000 card=0xc8673842 chip=0x062210de rev=0xa1 hdr=0x00

Would you need a xorg.conf "Section Device" entry with the second pci1 slot (something different than :1;0;0)?

AFAIK using the iGPU and Nvidia card together as one screen across multiple monitors will only work when using Hybrid graphics and then, only on Linux or Windows.

If you can get your second Nvidia graphics card detected, this link should point you in the right direction in regards to using both. I've used a very similar setup and configuration in the past.
