Не может получить доступ к Единице Ubuntu 14.04 (Гренок)

Я установил Единицу на своем HP 14 дюймов Chromebook, и это работало просто великолепно. Я обновил к Единице 14,04 внутренней части Единицы, но после 'перезапуска для окончания обновлений', я не мог запустить единицу с тех пор.

Это - то, что происходит после sudo startunity

chronos@localhost / $ sudo startunity

Это действительно сводит меня с ума! После того как я ввел sudo startunity в оболочку экран идет темный, как это было бы, когда это переходит к Единице, но затем возвращается к моему экрану ChromeOS.
