Ubuntu 16.04: занимает слишком много времени для загрузки
Моя система очень медленная загрузка. У меня нет SSD, но более 2 минут для загрузки кажется довольно медленным. Я просмотрел и нашел некоторые команды для анализа проблемы. Большинство ответов не говорят, что делать, когда что-то не так. Поэтому я добавил команду и результаты ниже. Было бы хорошо, если бы кто-нибудь мог сказать мне, что не так и как его решить.

2@asdfkjasdfjk вы внесли оба изменения и не было улучшения во время загрузки? Я добавил обновление к моему ответу. Пожалуйста, сделайте это и сообщите об этом. Пожалуйста, покажите мне terminal вывод free -h и swapon -s. – heynnema 5 July 2017 в 06:15

3да, оба изменения не улучшили время загрузки, также команда fsck не выдавала никаких ошибок. Я добавил вывод бесплатных и swapon-команд в вопрос под обновлением. благодаря – asdfkjasdfjk 5 July 2017 в 10:01
