Ok I'm going to move this to the restricted modules package for Feisty as the nvidia proprietary drivers are located there. If your xorg.conf says "nv" then what you're looking at in synaptic is most likely the feisty version of the open source drivers. I can't really tell you more, if you want to try to reinstall them it might fix it. Other than that, by moving it here hopefully someone else can possibly come up with another suggestion.
