Same with my Dell Inspiron 1720 ...

The problem seems to be related to the "Nvidia propietary driver", not the Ubuntu OS.

Everything (shut down, restart) work perfectly since I have removed all the Nvidia stuff, as in : http://askubuntu.com/questions/189347/how-can-i-uninstall-nvidia-proprietary-drivers

Ctrl+Alt+F1
          - Login with your username and password
$ sudo stop lightdm
          - Press Enter
$ sudo apt-get purge nvidia*
          - Y (yes) at the question
          - Press Enter
$ sudo apt-get install xserver-xorg-video-nouveau
          - Press Enter
$ sudo reboot

Done ! The opensource driver "nouveau" works perfectly (and better than the Nvidia one), so don't worry.
