Начала подвисать

[DoublePain]

Суть в том что Ubuntu начала подвисать, допустим пытаюсь выключить - и эффекта никакого, тоже самое с перезагрузкой. Помогает Alt+PrintScr REISUB.
Сегодня терминал повис на sudo aptitude safe-upgrade, запустил второй терминал-грузиться, виснет, система не отвечает. В каких логах искать проблему?

Под иксами стандартные

~/.xsessions-error
~/.xsession-errors.old

В xorg ничего плохого не нашёл. А вот в xsessions есть проблемы. Как это решаеться?

Гуглением по ошибкам из логов. По-другому никак.
