I installed some time ago elementary OS Freya. I'm fighting for a couple of days to get the correct configuration for my not typical multimonitor set

2 nvidia graphics cards GeForce GTX 660 Ti & GeForce 9800 GT

01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660 Ti] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 GT] (rev a2)

5 monitors: DELL 2407WFP (portrait), HP LP2465 (portrait) on the left, Samsung SyncMaster 305T (landscape) in the center, HP LP2465 (portrait), HP LP2465 (portrait) on the right. 2 from left and center one are connected to GeForce GTX 660 Ti, two on the right are connected to GeForce 9800 GT.

On nvidia autoconf only monitors on the left and center one are ok but two on the right are dark ... I can move cursor on them but nothin more. I realized that in this way I get nothing.

Right now I'm working on xorg.conf for this setup. I was looking for a similar configuration and came across this one. I use it a little as bit to make mine but I'm not sure if it is ok. I would greatly appreciate it if you kindly give me some hand with this configuration.

Nvidia has a application note describing using (2) Quadro cards with 4 displays. I have a working setup with a single quadro and 4 displays, using the MetaModes only option.

Option         "MetaModes" "1920x1080 +0+0, 1920x1080 +1920+0, 1920x1080 +0+1080, 1920x1080 +1920+1080"
