недавнее обновление nvidia-304 повредило систему

Ubuntu 16.04 nvidia-304 собственный драйвер, установленный и обновленный через Nvidia ppa (для GT 620)

Система хорошо работала в течение 6 месяцев, но недавно повредилась (не возможный закончить экран входа в систему) с обновлением nvidia-304, не удающимся создавать. любой совет относительно того, как зафиксировать это, очень ценился бы

apt purge nvidia* && apt install nvidia-304
