Laptop does not suspend when lid is closed

[Bruce Phillips]

$ lsb_release -rd

Description: Ubuntu 18.04 LTS
Release: 18.04

In Tweaks > Power, "Suspend when laptop lid is closed" is ON, but my laptop does not suspend when the lid is closed. The laptop is a Thinkpad P50.

When closing the laptop lid, no events show up in dmesg.

This is my /etc/systemd/login.conf:

I've been experiencing the same problem since friday on a Dell XPS 9560 laptop on Bionic. I created a different user account to test and laptop doesn't suspend, but if I switch that user to a Mate Desktop session it works fine.

These are the relevant lines on my logind.conf file:

~ cat /etc/systemd/logind.conf |grep -i lid
HandleLidSwitch=ignore
#HandleLidSwitchDocked=ignore
#LidSwitchIgnoreInhibited=yes

Curiously, I can see this config file was changed last (presumably due to an update?) just last friday june the 8th, which is perhaps too much of a coincidence:

/etc/systemd ~ ll
total 36K
-rw-r--r-- 1 root root 1.1K Apr 2 20:25 journald.conf
-rw-r--r-- 1 root root 1017 Jun 8 13:33 logind.conf
drwxr-xr-x 2 root root 4.0K Oct 4 2017 network
-rw-r--r-- 1 root root 601 Apr 12 12:12 resolved.conf
drwxr-xr-x 21 root root 4.0K Jun 11 08:18 system
-rw-r--r-- 1 root root 1.7K Apr 2 20:25 system.conf
-rw-r--r-- 1 root root 604 Apr 2 20:25 timesyncd.conf
drwxr-xr-x 3 root root 4.0K May 10 15:52 user
-rw-r--r-- 1 root root 1.2K Jul 12 2017 user.conf

This happens on:
  * Ubuntu gnome session
  * Vanilla gnome session
  * Unity 7 session

Suspend on lid closed works correctly on
  * Mate session

I do not mix DE's on the same user, always create a new one to use with it to avoid home folder pollution.

All gnome sessions above are on X btw, not Wayland.

Commenting out the line

 HandleLidSwitch=suspend

restores normal behaviour. Since I didn't change it to begin with, I gather an update did this judging by how its last modified date was the same day suspend-on-lidclose stopped working.
