После обновления системы перестал запускаться gnome

Собственно ситуация следующая.

После очередного обновления системы появляется следующая проблема.
export XSESSION="Gnome"
startx

после чего показывается волпейпер, курсор и экран начинает бешенно моргать, процесс X кушает 80% ресурсов системы и около 2 Гб памяти. На ctr+alt+backspace не реагирует
Причем если вместо гнома попытаться запустить xterm, все ок.
