To reconfigure the xserver run the command
sudo dpkg-reconfigure xserver-xorg

If you don't want the command to ask you any questions, but just do what 
it did during the install use this command instead:
sudo dpkg-reconfigure -phigh xserver-xorg

There are a couple lines in your xorg.0.log that show why you are having

The first set of lines is xorg trying to load the nvidia module for your 
video drivers.  Did you update the kernel recently?  If so, did you also 
update the restricted modules?  Perhaps you installed the proprietary 
nvidia drivers by hand?  If so, did you re-install for the new kernel?

I believe that your problem is a kernel module for the nvidia that is 
not for your currently running kernel.  I would suggest either using the 
nv or the vesa driver until you sort out your issues with the nvidia one.
