I am running Ubuntu 11.04. I have an NVidia GeForce GTX 295 card installed with driver version 295.53 installed. I had struggled with this for a while a few weeks ago, and gave up. However, last week, I came into work, and noticed both monitors were working. I thought one of my tech buddies helped me out (we are a small company, and I just spoke with him today. He thought it was still not working) so I went on my merry way happy that I had dual monitor support. Unfortunately, I crashed (tried to compile a program while running a large virtual box) the computer yesterday, and when it came back up, I was back to a single monitor again. I had not changed any settings or files related to any software installed.
TL;DR: Dual monitor support started working out of the blue, and upon reboot, disappears.
Any thoughts on where to go?
A few notes:
I understand about duplicate questions. I have tried a number of solutions from a wide range of websites, including this one, but none of them seem to help, or be relevant to my situation.
My xorg.conf file is as follows (which I assume was the correct mix of settings):

I would recommend using the nvidia's x configuration tool to accomplish this, as for as long as ive been hand editing xorg.conf's (since 2002) it seems to change drastically based on the drivers, card and distro xorg server and xrandr support.
For what it's worth, here's my xorg setup from ubuntu 10.04 LTS which has compositioning and acceleration enabled (I'm using compiz-fusion on it and twin view)
The key question to me based on your file is if you are trying to get twin view or two separate heads. in other words: one big spanning screen across both monitors? thats what my setup is doing.
I see you're using 295.53. Just to be safe could you try:
