This question was marked as an exact duplicate of an existing question.

According to Ubuntu Forums:

Unity 2D was removed from 12.10 onwards. We now have something called llvmpipe which has the purpose of providing Unity 3D on lower specified PCs.

I don't think there will be interest in resurrecting 2D development.

I know this is not a direct answer to the question posted, but it rather leaves you with two possible choices (if you seriously need Unity 2D):

  1. Reinstall and stick with 12.04 (currently 12.04.2).
  2. Use the "fallback" session in either 12.10 or 13.04.
