  1. I installed the last beta of kubuntu 15.04, but I cannot find “additional drivers” to install nvidia drivers. Is there a way to install the “additional drivers” program/app or do I need to install final version of kubuntu? I know I can install nvidia drivers directly, but then I do not get updates automatically

  2. Oh, sorry but I was on version 14.04 LTS… is there a way to install KDE5?
