Here's what I did:
I created a file /etc/acpi/events/lm_lid and wrote into it:

event=button/lid.*
action=/etc/acpi/lid.sh

I created a file /etc/acpi/lid.sh and wrote into it:

#!/bin/sh 
gnome-screensaver-command --lock

The good news are that this script is being executed when I close the lid. The bad news are that it doesn't lock the system. Any other command I put in the script is executed when I close the lid except the lock itself. When I run the script manually from command line the system locks.

What did I miss?

    I think your problem might be that that script is executed outside the X session you want to lock (and probably as another user) .You probably need gnome (I assume that you wanting to run gnome-screensaver is an indication you use gnome) to help you. – Henrik Dec 24 '18 at 12:38
  • @JothamB Have you solved the problem? – Dhruva May 12 at 5:55
  • I moved from Ubuntu 18.04 to Mint. Solved this problem and more. Much better distro. – JothamB May 13 at 10:09

I'm using Debian and faced similar problem, first, i wont recommend script because it doesn't work in lock screen.

if you are using gnome install gnome-tweaks and it has a option.

alternatively edit the /etc/systemd/logind.conf, just uncomment the HandleLidSwitch=suspend line.

this worked for me.

  • Thanks. I can suspend the system but I want to lock it. – JothamB Dec 24 '18 at 16:28
  • @JothamB There's a setting in Gnome settings under privacy, screen lock. Click on it and set the lock screen after blank for to the option screen turns off. – Kushagra Karira Dec 25 '18 at 17:23

Try downloading gnome-tweaks and there should be an option about locking when closing the lid.

To download gnome -tweaks do: sudo apt install gnome-tweaks-tool

You can also use this for tweaking things like right clicking and left clicking.

  • It only has an option to suspend. I want to lock without suspending. – JothamB Dec 27 '18 at 11:08
