I installed Ubuntu Kylin Theme but I want to restore the original login in screen for ubuntu, I tried to uninstall the theme, purge and reinstall the lightdm and also change the default to gdm with dpkg-reconfigure but I always get the Ubuntu Kylin login screen.
EDIT:
I tried to see the configuration in Ubuntu Tweak but only show the default login screen configuration even showing Ubuntu Kylin when I boot the computer.
