When laptop lid is closed, the desktop switches to external monitor (Ubuntu 20.04 Gnome)

Question

Instead, I want my laptop to suspend when the lid is closed (this is the behaviour currently if no external displays are connected)

I followed the steps in the answer - https://askubuntu.com/a/790136/785975 but that didn't work (maybe because of the updated Ubuntu version?)

Is there a fix for this in Ubuntu 20.04 for the default Gnome DE (I haven't tried with other DEs)?

Do you want it to suspend with the lid closed or something else? Did you check the settings already? — ChanganAuto, Jul 30 '21 at 16:06
Ah sorry if I wasn't too clear - I want the laptop to suspend; not switch the display over to the external monitor. And yes, I checked all relevant settings. — Pratyush Das, Jul 30 '21 at 16:07
I suggest installing Tweaks (gnome-tweaks) and confirm the relevant setting is enabled. — ChanganAuto, Jul 30 '21 at 16:13
I have gnome tweaks and "Suspend when laptop lid is closed" is enabled. — Pratyush Das, Jul 30 '21 at 16:25
Does it work as expected (suspend) if the external monitor isn't connected? — ChanganAuto, Jul 30 '21 at 16:26
Yes. It does. (Look at the question - I updated it a few minutes ago) — Pratyush Das, Jul 30 '21 at 17:25
I’ve tried the solution from the guide on Ubuntu 23.10 Mantic Minotaur. Unfortunately it does not work for me. But when I tried it on 23.04 Lunar Lobster, it did work. — BlueWolf, Dec 31 '23 at 20:23

It took me cca 2 hours to find the answer, which is not that bad for Ubuntu questions. Check out this post, it worked for me (Part III). https://apiraino.github.io/ubuntu-gnome-power/

The essential part is (after everything you have already done) to add the following line to /etc/systemd/logind.conf:

LidSwitchIgnoreInhibited=no

Then reboot and after that paradoxically modify the line in /etc/UPower/UPower.conf as follows:

IgnoreLid=true
