Артефакты и самопроизвольная перезагрузка системы

[yots2]

Привет всем. После 10-летнего использования Windows-XP решил установить Ubuntu, выделив для этого отдельные логические тома для / -root, swap и /home, в соответствии со всеми рекомендациями, указанными в разделе помощи. После первого же запуска и нескольких минут работы на экране появились "артефакты" в виде горизонтальных полос на весь экран, так что разглядеть практически ничего невозможно. Методом тыка определил, что если нажать на то место, где "Поиск на компьютере и в интернете", данное явление полностью или почти полностью пропадает. Иногда, сразу же за появлением артефактов следует перезагрузка компьютера. Закономерности во времени появления данных глюков не прослеживается. Погуглив несколько дней, я пришел к выводу, что это связано с видеокартой, а именно с драйверами к ней, но что делать, ума не приложу, так как мои знания в Linux приближаются к нулю. Если кто-то знает, как решить проблему, дайте ссылку на инструкцию. Вот мои параметры системы:

P.S. Пока писал это сообщение, компьютер перегрузился раза 2-3, и несколько раз колбасило изображение. Ввиду этого логи указал только за сегодня,- думаю, этого вполне достаточно.

[wajnon]

yots2,
судя по симптомам дело в видеокарте.

[yots2]

Думаете, приказала долго жить материнская плата (видеокарта встроенная), или можно подобрать более оптимальные драйвера?

[wajnon]

yots2,
дело в том что в дистрибутив УЖЕ включенные драйвера для Интел. Google говорит что эта карта не только у вас имеет проблемы:

[DimanBG]

wajnon, ты хотя бы смотрел сколько лет этим постам и в каких версиях Ubuntu?
yots2,
Оптимально будет дистр 32х 12.04 Попробуй, конечно 14.04 но с ядром не выше 3.19

[yots2]

DimanBG, 32х 12.04 LTS работает у меня уже час, глюков никаких не наблюдаю. Спасибо большое за помощь.

Пользователь решил продолжить мысль 15 Марта 2016, 16:34:10:Вот, блин, нормально же всё работало несколько часов. Установил Chromium, Opera, Krusader, Skype. Всё как по нотам, без нареканий. Нажал в Опере "Инспектировать элемент", чтоб скопировать класс элемента страницы, как БАЦ!... и перезагрузка. Так пробовал несколько раз, и каждый раз то же самое в том же месте. Может, у меня действительно что-то с материнской платой (10 лет, всё-таки). Спасибо всем, кто не пройдёт мимо.

Закрываю тему. Такое наблюдается только в Опере, поэтому считаю это багом Оперы.
