I tried changing theme at **/etc/lightdm/lightdm.conf** to **greeter-session=lightdm-gtk-greeter**, but the result was worse because typing password doesn't unlock the screen and no way to see what goes wrong. I am sure lightdm-gtk-greeter is installed because installation command shows it's installed.
Code: Select all
sudo apt-get install lightdm-gtk-greeter
