Whenever I boot up my Manjaro Cinnamon, some service is installed and run that creates a group named “autologin” and then proceeds to add all users to it.
As a result, I always need to remove that group manually because I really, really do not want any autologin feature on my computer.
How do I remove that feature, and prevent it from being re-installed at every update?
You can check in /var/lib/pacman/local for the install files if a package auto creates that group when updating or installing. Else you have to look thru enabled systemd services to find a clue. Calamares installer might add the user to autologin if that was checked.
Turned out that it is a lightdm thingie. I now worked around it by backing up “/etc/systemd/system/multi-user.target.wants/add-autologin-group.service”, and replace it with an empty file that I locked with chattr +i.
Not the most elegant way to go about it perhaps but hey, if it works, it works, right?
