Перезапускается gnome3

Неизвестно по какой причине внезапно меня выкидывает на 1 TTY, а затем gnome3 запускается с нуля. Тестинг репозитории отключены.

Из запущенного софта:
Плеер Last.fm, Deluge, Pidgin, Chromium, GoldenDict. Использую свободные видеодрайвера ATI.
Также иногда система подвисает. В других дистрибутивах такого нет.
Подскажите куда копать?
Проблема так и не решилась. Кажется проблема именно в гноме3, но странно что второй раз подряд в логах фигурирует goldendict. Но намного чаще его не было.
