There are three drivers available for NVidia cards:
'nv' is a very basic open source driver produced by NVidia essentially
in order to make the graphics card work by enough that the proprietary
NVidia driver can be installed. It supports very basic 2D graphics and
Historically, this is the default driver used for NVidia chipsets on
'The NVidia binary driver' is the 'proper' driver released by NVidia,
supporting all the features of the card like 3D acceleration and
multi-monitor support. It's not free-as-in-freedom so cannot be
shipped as part of the default install - it needs to be installed
manually after installation.
Novau is an attempt to write an open-source version of the NVidia
binary driver. It aims to support all the fancy bits that the binary
driver does, but without the non-free code. I didn't notice this driver
becoming considered stable enough to go into Ubuntu, but apparently it

These are two incremental versions of the NVidia binary drivers. The
'Additional Drivers' tool will, in general, only show you those drivers
since they're the ones considered 'additional'. The post-release
