The version in cache is much likely the previously installed version
that worked.

Those steps a strictly KISS:

  change to the cache directory

    cd /var/cache/apt/archives/

  remove all nvidia packages

    sudo apt-get purge $(dpkg -l nvidia* | grep ii | cut -d" " -f3)

  just in case, update the index, assuming hard dependencies should be
  missing

    sudo apt-get update

  install just the absolutely dkms related necessary package of the
  version, the OP knows that it works on 12.04 and that might be the
  version used with 14.04, too

    sudo apt --no-install-recommends install nvidia-304*131*deb

  if this should work and the OP should miss a settings dialogue, try
  installing

    sudo apt --no-install-recommends install nvidia-settings_331*deb

  too.

  If everything works, prevent the package or two packages against
  upgrading.

  Else if ;), run

    sudo apt-get purge nvidia-settings and hold/lock the
    remaining package.
