Help using both QNIX 2650x1440 and acer 1680x1050 with NVIDIA?

I have to preface this with the fact that I'm a Linux newb. I've learned a lot in a couple of weeks, but so far this has me stumped.

I've been trying for over a week to find the solution that will let me use two monitors. They are a QNIX 2650x1440 and an acer 1680x1050. I can make either work individually, but can't seem to figure out how to get them on at the same time. II can get dual monitors under the default drivers, the problem is when I install the NVIDIA proprietary drivers. I have two GTX 680's and I"ve tried connecting both monitors to one
I am presently on Kubuntu, but I've tried Ubuntu and Linux Mint also.

Thank you!!!!!

Here's how I got the QNIX to work:

After all weekend of trials and errors (lots of errors), I found the solution that works. The main problem was that, because the QNIX monitor isn't directly supported, the NVIDIA configuration utility could not create an xorg.conf file that would work. Also complicating maters was that almost all online references assume that NVIDIA has "Twinview", which as far as I can tell, is not a select-able option in the 331 drivers.

Here's what allows me to have Full resolution on both monitors.
