Гном Ubuntu замедляет начальную загрузку (более чем минута), 15.04

Я испытываю некоторое необычное время начальной загрузки в своей среде гнома. Я имею, выполнил bootchart и dsmeg, но я не уверен, что извлечь из него.

Вот журнал dsmeg приблизительно во время, метки времени сходят с ума

Также вот моя диаграмма начальной загрузки. Похоже, что это имеет в 20 вторых раз или что-то? http://imgur.com/bnnWi39 я не могу встроить изображение из-за своей репутации, таким образом, я оставляю ссылку imgur.

Кроме того, вот результат, systemd-проанализируйте:
