Thank you, this was double checking, as i got a bit confused with the 
remainder of the information ;)

My experience with teamviewer is that in case of a version mismatch it 
will complain and refuse to work at all (and tell you to upgrade).

Both nouveau and the driver from NVidia have pro and con. I usually use 
the nvidia provided driver although nouveau has made great steps in the 
last years.
You could try with the NVidia provided driver (which is different yet 
from nvidiafb).

In Debian this is package nvidia-driver to obtain the NVidia proprietary 
driver. I expect Ubuntu to use a similar name.
