Você precisa remover os drivers antigos primeiro. Executar
sudo apt-get purge nvidia*
e tente novamente.
Eu tentei instalar qualquer versão dos drivers da Nvidia gpu em uma tentativa de se afastar do 331, o que causou e emitiu a atualização do kernel e não foi corrigido. Eu tentei usar o método de drivers adicionais e através do terminal. Não consegui encontrar ninguém que tenha tido este problema.
Isso é o que recebo do terminal:
sudo apt-get install nvidia-352

Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
