First purge the package and remove the PPA.

sudo apt-get purge lightdm-gtk-greeter*

sudo add-apt-repository --remove ppa:lightdm-gtk-greeter-team/stable

sudo apt-get update

Then edit the file that reads the greeter.

gksudo gedit /etc/lightdm/lightdm.conf.d/10-ubuntu.conf

change this line greeter-session=lightdm-gtk-greeter to this greeter-session=unity-greeter

if the line above does not exist, add it.

if above file/path does not exits (depends on Ubuntu version) try this one

gksudo gedit /etc/lightdm/lightdm.conf

Then reconfigure both DM and greeter

sudo dpkg-reconfigure lightdm unity-greeter

Reboot your PC.
