Talvez seja um pouco tarde demais, mas acabei de encontrar o mesmo problema, de acordo com: link ,
Eu apenas dkms meu driver nvidia, então ele funcionou, é algo como:
sudo dkms install -k 4.10.0-11-generic -m nvidia-378/378.13
Ubuntu 17.10. Toda vez que eu faço o login com a senha certa, ele volta para a tela de login. Mas startx pode funcionar.
Percebi que esse problema existe há muito tempo e, na verdade, tentei
chmod / chown a .Xauthority , .ICEauthority
sudo chmod a+wt /tmp
não tem drivers nvidia (eu acho)
Além disso, se nenhum método puder funcionar, é possível obter os dados de Access-Your-Private-Data sem digitar a frase secreta? Eu só tenho minha senha.
