I've found a solution to autostart the lightdm-greeter for user login. Following the steps below: My solution was to run: rm /etc/systemd/system/default.target systemctl set-default graphical.target This will replace the default target file, which in my case must have prevented systemd from reaching the graphical target, with a symlink to the graphical target. After this, lightdm (and gdm when selected with dpkg-reconfigure) starts automatically. /etc/X11/default-display-manager was already set to the correct value so this appears to be a different root cause from OP's. You will have to install the following: # apt install lightdm-gtk-greeter lightdm

I'm also interested to get the login screen working, but the post above with apt-get remove nodm and apt-get -y install lightdm, then reboot. But did not work, all I get after reboot is login prompt, and after login have to manually issue startx command.
