OK, did this but it did not fix the problem.

I am always unsure of the results of this command. Does this do the same 
thing as letting the software-updater do an update?

This is from the sys.log:

Nov  5 08:47:46 Jims-1404 kernel: [ 1543.963922] NVRM: API mismatch: the 
client has the version 304.132, but
Nov  5 08:47:46 Jims-1404 kernel: [ 1543.963922] NVRM: this kernel 
module has the version 304.131.  Please
Nov  5 08:47:46 Jims-1404 kernel: [ 1543.963922] NVRM: make sure that 
this kernel module and all NVIDIA driver
Nov  5 08:47:46 Jims-1404 kernel: [ 1543.963922] NVRM: components have 
the same version.

So if this is the problem do I purge the nvidia driver?

So if I do that I assume I will re-boot to some low res driver and the 
try to install the nvidia driver. But which one .131 or .132 or will the 
installer pick the right one.

I'm a little bit lost here as I have never had this problem before.
