Не удалить главный Nvidia пакет

При попытке переключиться 14.10 на systemd я столкнулся с ситуацией: Я не могу удалить 'главный Nvidia' пакет, и он предотвращает меня для установки или выскочки или systemd, поэтому теперь моя машина не перезагрузит. Как я могу вынудить dpkg удалить тот немой пакет?
