Яркий Kubuntu 15.04 - Nvidia GTX 660M (Optimus снова)

Я очень сожалею, что вытягиваю эту тему снова, но "Я все еще не нашел то, что я ищу...".

Я попробовал тонны решений с несколькими поведениями, и я не могу получить его работа правильно.

В первую очередь, я должен все еще использовать шмеля в ярком или существует рабочая альтернатива как primus? Я попробовал primus, и мой kubuntu внезапно прекратил работать. У меня есть средний опыт в Linux ОС, но я собираюсь действительно любить его. - Только эта вещь, делающая меня так подавленный.

Я боюсь, что должен переустановить причину kubuntu, мои действия по установке для драйверов Nvidia пошли неправильным путем - но я готов сделать это.

Сообщите мне то, что может я делать и что должно я делать.

P.S. Lenovo Y580 Nvidia GTX 660M (Windows7 + Kubuntu)

Вот то, что я получаю:
