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):
