Maintenant le redémarrage est possible.

En cas de problème ex. écran noir avec seulement la flèche de la souris:

• le login est possible en console pour faire des modifs
• si le mountages ne sont pas effectués: installer “lightdm” et le désinstaller

  $ sudo apt-get install lightdm
  $ sudo apt-get remove lightdm
