Durante a instalação do Ubuntu, os drivers serão instalados a partir do main e do restricted repository, restricted contém os drivers proprietários.
O software non-free deve existir no multiverse repo.

Software não livre:
Nonfree software is any software that is not free. Its use, redistribution or modification is prohibited, or requires you to ask for permission, or is restricted so much that you effectively can't do it freely.
Software proprietário:
Proprietary software is another name for nonfree software. In the past we subdivided nonfree software into “semifree software”, which could be modified and redistributed noncommercially, and “proprietary software”, which could not be. But we have dropped that distinction and now use “proprietary software” as synonymous with nonfree software.
