I'm a newbie and not a programmer so please be gentle with me. I've got Proxmox up and running on an old MacBook Air and am trying to figure out how to make it so it stays active when the lid is closed. I've searched but didn't find any solution. I saw something about editing the /etc/systemd/logind.conf file, but was unable to locate it as the sudo -H gedit /etc/systemd/logind.conf command wasn't recognized. Thank you!
