Plasmashell прекратил работать

Я использую kubuntu 15.04. Внезапно (не делая обновления), когда я вхожу в систему, моя плазма не запускается. Я нахожусь в рабочем столе с моими открытыми приложениями, но никакие панели, никакое меню, никакой фон.

sudo plasmashell работы (но как корень), не как обычный пользователь. Я попытаюсь обновить теперь, но я немного волнуюсь, что должен зафиксировать это сначала. Возможно, я должен проверить конкретный журнал?

Это могло быть проблемой полномочий? Я использовал дельфина в качестве корня для решения полномочий записи резервной проблемы, возможно, который был плохой идеей.

- ОБНОВЛЕНИЕ

Я изменил владение всех файлов в/home/me мне. Впоследствии, пытаясь выполнить plasmashell:

- UPDATE2
