I’m on Ubuntu 20.04. I’ve just edited
/etc/systemd/sleep.conf to disable “suspend” mode. The UI’s “Settings” picked up the change after a short while, by no longer displaying suspend-related options.
Does that mean that systemd has also quickly noticed the change automatically, or is there something I have to do to make the changes effective? (I’ve checked the manpages, and nothing is mentioned about it).
If it’s automatic, is there somewhere that logs it? I’ve checked
journalctl -u systemd-suspend.service and there’s nothing obvious.
