As the title suggests I'm trying to create a dual monitor setup. I have the nVidia 8800 GT, but I can't seem to find the other BusID:
$ lspci | grep VGA
03:00.0 VGA compatible controller: nVidia Corporation GEForce 8800 GT (rev a2)
I know it's located at 01:00.0, but why doesn't it show up? I tried rebooting with both monitors plugged in and on, but then it couldn't find /dev/sda3 (root partition, luks). I tried booting up 3 times, but all three times ran into the same problem. I was only able to boot into the computer when I turned off the second monitor.
I'm also trying to configure xorg.conf, but I'm not quite sure how to. They have different resolutions. From what I gather, there are two ways to do it with an nvidia card. I can either use twinview in the screen section or create two monitors and screens, and then put them both in serverlayout, is that correct?
---Edit---
The first screen has a resolution of 1280x1024, and the other is 1600x900.

I have the same graphics card and cannot get dual monitor setup working. How did you finally solve the problem?

Does it not show up when you run nvidia-settings?

If the 8800 has two outputs, both of them have the same BusID, only the Screen variable differs. So you would have two Device sections, different identifiers, BusID of "PCI:3:0:0", and Screen of "0" and "1"

Thx ngoonee, I finally got it working! Now both monitors show up in nvidia-settings and I can drag them around.
Here's my working xorg.conf, if anybody needs it.
