What actually happens if you just install lightdm is that you have a display manager, but no session manager or window manager. You get a default login screen that proclaims "debian⁸", and it does accept the pi:raspberry credentials, but it cannot launch a GUI session.
To install a GUI on the Lite image, I tried:
That is miles away from what you get in a full image (and it is closer to upstream Debian than to RPF PIXEL) but it at least it worked for me. (I do not understand why a similar attempt failed for Parkview upthread.) Enthusiasts may wish to review stage3 of pi-gen for some of the other differences between Full and Lite images. https://github.com/RPi-Distro/pi-gen/tree/dev/stage3
Code: Select all
sudo apt-get update sudo apt-get install xinit lxde gksu lightdm
