Hi, I have installed a new system with Debian Jessie and Xfce. When I try to disable lightdm via systemctl, X11 is stopped as expected, but after the next restart, the graphical login is back. I do not want to uninstall lightdm, but just disable the automatic start of X11 and lightdm. What is the way to do this with systemd? "systemctl disable lightdm.service" seems to not do it. Best regards, Reiner
