No Ubuntu 15.04 Ao usar quase todos os aplicativos do gnome depois de alguns segundos, tudo se fecha quando voltamos ao prompt de login. Eu tentei com o nouveau e o driver da Nvidia, mas nenhuma mudança. O Chrome está funcionando bem, o Krusader e o Terminal para. lspci me dá:

Kernel driver in use: nouveau
Encontrei poucas informações relacionadas no dmesg:
nvidia: module license 'NVIDIA' taints kernel.

Estava funcionando antes até alguma atualização. Eu olho em muitos fóruns, mas não consigo encontrar nada de útil, então qualquer conselho é bem-vindo Obrigado!
