Suspend does not work when lid is closed on lenovo W530

[Gerd Grundke]

After upgrading to Ubuntu 17.10 closing the lid of my Lenovo W530 does no longer suspend my machine.

I checked the power settings using tweak
-> Suspend, when lid is closed is ON

I ran the following commands

sudo apt install gksu
xhost si:localuser:root
gksudo gedit /etc/systemd/logind.conf

I changed the setting of HandleSuspendKey = hybernate to suspend
(Why was this still set to hybernate, when tweak power settings says suspend?)

[Login]
#HandleSuspendKey=suspend

after saving I ran
sudo systemctl restart systemd-logind

But still no action is performed, when I close the lid.

Checking System Settings for power
-> suspend when on battery after 15 minutes

This works perfect after the 15 min idle time.

Somehow no action is performed when I close my lid.
