Well i have had ubuntu installed a little over 2 years. All documentation for all my other problems i have found online somewhere or another. Anyway i had the same system for 2 years and today my motherboard decides to go out on me. Well i get a new Asus M4A78 Pro Motherboard and it works great. Ubuntu is my only OS i will run and i had dual monitors setup on my last system. Well i kinda figured i could just reinstall and setup dual monitors using nvidia-settings. Problem is, nvidia settings doesnt let me select twinview. I used xirama before but could not get that to work either on my new system. I have 3 videocards. An onboard, pci express nvidia 7300 LE, and a nvidia 5500. If i can set it up to only use the pci express and the onboard, or just pci express that would be great. Before the only way i could get it to work was with another video card. Can someone help me get this working, i have google searched all day and tried everything i can think of and still same problems. Here is my xorg.conf i am using restricted driver 177.

I have ordered that same board for installation in an upgrade I am doing and as far as I can tell it has a AMD 780G chipset which I think is ATI, not Nvidia.

The Asus Nvidia board equivalent is the M4N78 Pro. Sorry I am not familiar enough with the inner workings of these chipsets to help but shouldn't it being ATI instead of Nvidia make a difference with your settings?

I got a laptop with nvidia working with two monitors recently, (or a monitor and a projec tor) and all I did was go into 'Applications'-->'Add/Remove Programs' and install the latest nvidia driver and some other random nvidia related stuff, (sorry bit I wish I could remember exactly).
Then I followed the instructions and ran the commands from the Hardy Heron Ubuntuguide (http://ubuntuguide.org/wiki/Ubuntu:Hardy), specifically, 1.8.2 Configuring multiple monitors with a nVidia graphics card (http://ubuntuguide.org/wiki/Ubuntu:Hardy#Configuring_multiple_monitors_with_a_ nVidia_graphics_card) and in a few minutes we were easily able to do anything we wanted with another monitor or a projector.

I hope that info will be helpful.
