I am trying to change my laptop's lid close behavior following this article: http://tipsonubuntu.com/2018/04/28/change-lid-close-action-ubuntu-18-04-lts/
When I get to run:
systemctl restart systemd-logind.service
my system freezes and gets stuck.
What am I doing wrong here? Is there a simpler solution?
Restarting systemd-logind is not good for your graphical session(s). I would have expected the session to crash and log you out instead, but that's not what they imply either. I have no idea what they were doing. I would suggest rebooting instead of running the restart command.
In case you set it to hibernate, make sure that you have also tested hibernation, e.g. by running this command:
systemctl hibernate
