Зависает Xubuntu 15.04 на Asus X551MA

[yustnip]

Давно наболевший вопрос, который надо как-то решить. Есть Asus X551MA:

В течение 1-2 дней (может и чаще) система намертво зависает без явной причины, мыши и клавиатура (в т.ч. хоткеи не работают). Для перезагрузки только кнопка включения.

Подскажите, пожалуйста, как правильно отловить этот баг?

yustnip, браузер chrome?

[yustnip]

На данный момент Яндекс.Браузер, но в Хромиуме то же самое, Хром не использовал.

[suslikk]

yustnip, попробуйте firefox попользоваться, мне помогло

[yustnip]

Спасибо за совет, но не могу , для работы нужна хромовская панель для разработчиков.

На всякий случай упомяну, одновременно запущен редактор Атом, он базе Хромиума тоже.
Пользователь решил продолжить мысль 10 Сентября 2015, 16:44:16:Поставил обычный Хром. Не особо верю, что поможет, но вдруг.

[yustnip]

Ну, сутки без фриза, ура! Почитал в сети много жалоб на зависшую систему от Хрома. Посмотрим, еще видел совет 32-х битную версию попробовать.

[yustnip]

Продолжаю свое исследование. И с 64-битным и с 32-битным Хромами система все-равно фризится, решил все-таки некоторое время поиспользовать Firefox, сейчас уже и не знаю, что лучше с Хромом и с зависаниями или с ФФ и без.

[yustnip]

В очередной раз продолжаю свою "песнь боли". Firefox не помог, тоже фриз через сутки аптайма. Правда в этот же момент был включен Atom, но я уже совсем не уверен, что причина в Хроме.

Получается никак не отловить причину? И ждать новой версии Убунты в октябре как шанс на избавление от зависаний?
Пользователь решил продолжить мысль 16 Сентября 2015, 13:39:56:И еще один вопрос, а есть ли смысл поставить 32-х битную систему, может ли это помочь?

Попробуйте, почему бы и нет. Я бы посоветовал также Xubuntu 14.04.3, если некритично, то лучше использовать LTS, а не проходную версию ..Ещё вариант - уже на 32-битной ОС поменять композитный менеджер на комптон.

[yustnip]

Спасибо за ответ. В LTS-версии у меня совсем беда с регулировкой яркости, всегда 100%. Поэтому и использую проходную.

[iCloud]

Была подобная проблема. Но после апдейтов на днях и установки ядра 4.2 падения прекратились. Попробуйте тоже ядро обновить.

[yustnip]

Это хорошо, буду ждать апдейтов. Новое ядро пробовал ставить, но оно не дружит с дровами на мой Wi-Fi, а через провод работать нет возможности.

Суда, например, глядели - http://blog.reext.ru/2014/09/noutbuk-asus-x551ma-ubuntu-14-04/?
Помоему лучше один раз настроить всё правильно и потратить время на допил ubuntu 14.04, чем так мучится на пятнашке, ожидая апдейтов, которые ох не факт что помогут.
