Disabling suspend when laptop closes on Ubuntu 24.04.1

Question

I've set up an old Dell Inc. Latitude E6410 with Ubuntu 24.04.1 with the intention of using it as a printer an Plex server. The problem is that it suspends when I shut the lid. I would like it to not do that. In my research on the issue, I've found many recommendations to use Tweaks to disable the suspension but when I install the current version of it, there is no such option available in it. No such option is available in the Power sections of Settings either. Is there a way to do this in this version of Ubuntu?

Answer 1

Quoted directly from this answer:

1. Open the /etc/systemd/logind.conf file in a text editor as root, for example,

   sudoedit /etc/systemd/logind.conf
   

2. If HandleLidSwitch is not set to ignore then change it:

   HandleLidSwitch=ignore
   

   Make sure it's not commented out (it is commented out if it is preceded by the symbol #) or add it if it is missing.

3. Restart the systemd daemon (be aware that this will log you off) with this command:

   sudo systemctl restart systemd-logind
   

   or from 15.04 onwards:

   sudo service systemd-logind restart
