Я только что обновил ноутбук до Ubuntu 16.04, и теперь я вижу следующую проблему. В случайные моменты (но когда происходит какая-то графическая активность, например, открытие окна) дисплей искажается и компьютер зависает. Единственное, что можно сделать, это принудительно выключить его; что, конечно, теряет все записи журнала ядра, которые могли быть.
Что я могу с этим сделать? dmesg (после загрузки) выдает несколько зловещих на вид трассировок стека, связанных с графикой:

Переустановка драйверов X, как в16.04 - Как очистить драйверы Intel по умолчанию и переустановить графические драйверы Intelне помогло. В предыдущих версиях Ubuntu этой проблемы не было, хотя некоторые 3D-операции (например, вращающийся куб рабочего стола) не совсем правильно выполняли преобразования перспективы.
решение1
Мне это помогло:
открытое программное обеспечение и обновления
