Solved problem, but not sure what did it or if it's permanent.
I added an old xconf.xorg file, because there wasn't one. I then restarted the computer but nothing happened. I installed nvidia-current and nvidia-settings. I them logged out of x using ctrl+alt+f1 logged in as root and ran
it said that it created an xconf file. I restarted and logged back in, the opening title was very basic - just the words Linux Mint, and when I checked the file, it was the same one I had added. But now Nvidia-settings is acting right and no longer telling me that I am not using their driver. The old file shows an old nvidia card (7500) that I had been using when I created that file and nvidia-settings has detected the newer nvidia (8800) card that I am now using.
Should I remove the file I added to /etc/x11 and start over again or leave well enough alone? Right now the resolution and refresh are what they should be and my screen is no longer jumping, but I have no idea why it happened in the first place. I have not updated anything recently.
