Disable suspend mode when closing the lid

As I 　 am running Ubuntu 20.04 on my old laptop, I want to disable the suspend mode when I close the lid. Here is how I did it:

1. Open the file /etc/systemd/logind.conf with your favorite text editor. I use vim:

   sudo vim /etc/systemd/logind.conf

2. Find the line #HandleLidSwitch=suspend which is default behavior. Uncomment it and change it to HandleLidSwitch=ignore.

tip

There are other options you can set:

• suspend: The system will suspend
• hibernate: The system will hibernate
• poweroff: The system will power off
• lock: The system will lock the screen
• ignore: The system will do nothing
