Что было сделано.
Ubuntu 14/04.03 скачана с этого сайта, обновилась
до 04
Графический стек и ядро обновлено командой
sudo apt-get install linux-generic-lts-wily xserver-xorg-lts-wily libgl1-mesa-glx-lts-wily libglapi-mesa-lts-wily libwayland-egl1-mesa-lts-wily libgl1-mesa-glx-lts-wily:i386
Больше ничего не предпринималось.
Были фризауты, буду решать.
Всем спасибо.
