You were right. That was what was missing indeed. Synaptic,
linux-ubuntu-modules for the latest kernel installed, reboot and
everything fine.

Though, I do not understand how such a relevant package doesn't come
"attached" as a dependency when updating the system to a new kernel.
People cannot re-check again and again which packages are present and
which ones aren't at a certain moment... (in my honest opinion),
specially when we talking about people that don't care very much about
techs, but just a system ready for working.

Thank you very much, man.
