Eu rodei o Debian 8 Jessie no meu laptop Sony Vaio. Ele tem um chip gráfico Nvidia Geforce GT 640M LE .
Eu segui o artigo oficial do Debian Wiki para instalar o nvidia-drivers em vez do nouveau:
Agora estou executando o Nvidia Driver 352.79 , que deve ser compatível com a minha GPU de acordo com as páginas wiki mencionadas.
Após a instalação eu corri nvidia-xconfig que criou um /etc/X11/xorg.conf para mim automaticamente:

Screen 0 "Screen0" 0 0

O problema é que quando eu inicializo, não consigo ver o ambiente de desktop - aqui está o completo Xorg.0.log :
