Actually, nvidia-settings usually doesn't touch /etc/X11/xorg.conf. It 
sets a per user X configuration in the users home directory, ~/.nvidia-
settings-rc. Boot into console mode and delete or rename ~/.nvidia-
settings-rc. And if you ever have run nvidia-settings as root (which you 
should not do), you should delete 
/root/.nvidia-settings-rc if it exists.

These probably are the files you'd want examine.

~/.nvidia-settings-rc (also possibly in /root)
~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml and xfce4-
session.xml

I would try deleting the nvidia.settings-rc file first, though.
