Installing gdm package helps.
Run dpkg-reconfigure gdm.

sudo apt-get install lightdm lightdm-gtk-theme
sudo apt-get install gnome-shell
sudo dpkg-reconfigure gdm

sudo /usr/lib/lightdm/lightdm-set-defaults -g lightdm-gtk-greeter
sudo /usr/lib/lightdm/lightdm-set-defaults -d -m true -g unity-greeter

restart "sudo shutdown -r now"
