Not sure about ATI, but when you purge the nVidia driver it takes Unity 
with it so I had to reinstall unity-desktop afterwards. If you want 
lightdm but are now using gdm, maybe it happened because unity-desktop 
was uninstalled and you just installed gnome-shell, your can reset:

sudo dpkg-reconfigure gdm

and select lightdm from the list.
