Preventing Proxmox on a Laptop from Suspending When the Lid is Closed

To prevent Proxmox on a laptop from suspending when the lid is closed, edit the /etc/systemd/logind.conf file to set HandleLidSwitch=ignore, HandleLidSwitchExternalPower=ignore, and HandleLidSwitchDocked=ignore. Uncomment these lines by removing the ‘#’ symbol, then save the file and restart the systemd-logind service with systemctl restart systemd-logind or reboot the system for the changes to take effect. 

Step-by-step Guide:

1. Open the configuration file: Open the logind.conf file using a text editor such as nano or vim:bashsudo nano /etc/systemd/logind.conf
2. Modify the settings: Find the following lines. If they are commented out (start with a ‘#’), remove the ‘#’ to uncomment them.
   • #HandleLidSwitch=suspend becomes HandleLidSwitch=ignore
   • #HandleLidSwitchExternalPower=suspend becomes HandleLidSwitchExternalPower=ignore
   • #HandleLidSwitchDocked=suspend becomes HandleLidSwitchDocked=ignore
3. Save and exit: Save the changes to the file and exit the editor.
4. Apply the changes: Restart the systemd-logind service for the new settings to become active:bashsudo systemctl restart systemd-logind Alternatively, you can reboot the Proxmox system. 

After these steps, closing the laptop lid will no longer cause the system to suspend, allowing Proxmox to remain accessible.
