Eu tenho um problema com 14.04 , minha máquina não voltaria como de costume para me mostrar o prompt de senha, mas exibia alguma mensagem que não continha muita informação em uma tela de shell.
Então, eu liguei a minha máquina e na inicialização, eu não cheguei na tela de login do X11, mas em vez disso, ele me lança para um login no shell. Eu tentei reiniciar sudo service lighdm start manualmente, mas isso só me deixa uma tela preta com um cursor piscando no canto superior esquerdo. Agora eu posso pegar meu X de volta? Eu não sei o que aconteceu, em /var/log/Xorg.0.log eu vejo algo como Device(s) dtected, but none match those in the config file - como posso ajustar isso para minhas duas telas para combinar? Meu /etc/X11/xorg.conf se parece com:

nvidia-331 is already the newest version.
Então eu fiz um sudo apt-get remove nvidia-331 seguido por um sudo apt-get install nvidia-331
Como indicamos através dos comentários que os drivers da NVIDIA não estão instalados, tente reinstalar os drivers nvidia seguindo o documento vinculado na seção Instalação sem o X / do console
sudo apt-get install --reinstall nvidia-331 fez o truque. (Marque a Edição 2)
