Sometimes people install/remove stuff over the life of their system
which results in one of the critical packages for operation to get
removed. You can ensure that everything that should be installed is
installed with this pair of commands (not the caret):-
sudo apt-get update
sudo apt-get install ubuntu-desktop^
I would run that and observe if any packages get _installed_ as they
were missing which may lead to some of the issues you're seeing.

I would backup and remove your /etc/X11/xorg.conf and let X figure out
your screen setup automagically, then perhaps use nvidia-settings to
fiddle about with the layout.

That looks like an incorrectly formatted line in your x session startup
somewhere?

Removing xorg.conf will probably work this out.
