Ubuntu Server - Laptop Lid Ignore
Use Your Laptop As A Server Tested on : Ubuntu 20.04 LTS To disable entering the sleep mode I had to edit the /etc/systemd/logind.conf file and modify the line: Just uncomment the line by removing # from this : #HandleLidSwitch=suspend #LidSwitchIgnoreInhibited=no #HandleLidSwitchDocked=ignore to this : HandleLidSwitch=ignore LidSwitchIgnoreInhibited=no HandleLidSwitchDocked=ignore Then restart the OS via: sudo service systemd-logind restart Then you can close the laptop lid .
