Yes, exactly that seems to be the case here.

Either the drivers coming with Ubuntu should be sufficient or you should use a
PPA to get bleeding edge drivers.

As Alex already noted as well the -pro drivers are for workstation use cases
where the user has a specific version of a distribution.

Marking this bug as invalid for now.
