You had a PAE kernel for which the headers were not installed

As a result, nvidia could not be built

Therefore Bumblebee autodetected nouveau and uses that instead

Ubuntu ships with horrible outdated nouveau drivers so that did not work

After rebuilding the nvidia driver, nouveau was still loaded. Since that takes precedence over "nvidia is available for loading"in auto-detection mode, the nvidia driver was not used.
