Plasmashell прекратил работу

Я использую kubuntu 15.04. Внезапно (без обновления), когда я вхожу в систему, моя плазма не начинается. Я нахожусь на рабочем столе с открытыми приложениями, но нет панелей, нет меню, нет фона.

sudo plasmashell работает (но как корень), а не как обычный пользователь. Сейчас я попробую обновиться, но я немного волнуюсь, что сначала должен исправить это. Может быть, я должен проверить конкретный журнал?

Может ли это быть проблемой разрешений? Я использовал Dolphin в качестве корня для разрешения разрешений на запись в резервную копию, возможно, это была плохая идея.

- UPDATE

Я изменил право собственности на все файлы в / домой / я про себя. Впоследствии, пытаясь запустить plasmashell:

Недавно я установил свою переменную DL_LIBRARY_PATH в .bashrc. Может ли это вмешательство? (смотря на этот bugreport)

- UPDATE2

Я создал нового пользователя. Плазма отлично подходит для этого пользователя. Это немного раздражает, чтобы снова выполнять все настройки моего рабочего стола, но нормально ... Я предполагаю, что это была проблема разрешения? Нет подсказки ...
