csd-power seems to be preventing laptop from suspending after using external monitor

Issue
After unplugging an external monitor multiple days ago, csd seems to be preventing my laptop from sleeping on lid close.

Steps to reproduce

• Make sure that your laptop can properly suspend when closing the lid
• Keep it powered on when plugging it in to a monitor.
• Close lid.
• Open lid and unplug from monitor

Expected behaviour

• The suspend function will operate as it did before using the monitor

Actual Behavior

• Suspend only makes the computer idle, as if a monitor is still plugged in.

Other information
List of blocking inhibitors. This was printed while the laptop was unplugged from the monitor after multiple reboots.

2 inhibitors listed.

I have attempted to use logind.conf to try to remedy this but it never recognizes my changes even after multiple reboots. I have set the session manager to default to logind, but that doesn't work.

org.cinnamon.desktop.session session-manager-uses-logind true
org.cinnamon.desktop.session session-name 'cinnamon'
org.cinnamon.desktop.session settings-daemon-uses-logind true
org.cinnamon.desktop.session idle-delay uint32 600
org.cinnamon.desktop.session screensaver-uses-logind false

logind.conf:

#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root

HandleLidSwitch=suspend
HandleLidSwitchDocked=suspend
#PowerKeyIgnoreInhibited=no

#HibernateKeyIgnoreInhibited=no
LidSwitchIgnoreInhibited=no

This does seem to be a problem with Cinnamon/csd-power. I have AWM and Mate install beside Cinnamon and neither have this issue. Here is a related post on the systemd github:
systemd/systemd#7137

I have also installed Mint 18.3 with cinnamon on a live usb and tried sleeping on lid close, and it works fine. It even lists all the same inhibitors as my main install. Currently all of my power settings are to suspend on lid close regardless of if AC or External monitor is plugged in.

I have tried both LidSwitchIgnoreInhibited=no and LidSwitchIgnoreInhibited=yes in my logind.conf file and neither has worked. When this first started happening a week or so ago, it would sporadically suspend correctly but it hasn't at all recently.

 * 64 bit

My issue is exactly opposite, but I guess there is a connection.

My laptop is set to do nothing on lid close while on A/C power and not to perform lid close action with external monitor attached. However, csd-power removes lid switch inhibitor after I detach my monitor, and once I close the lid (while still on the A/C) my laptop suspends.

What happens when you repeat that, but with no AC power? This was a long time ago so I don't remember whether I had power in when I unplugged my laptop or not.

It took reinstalling Mint to fix this issue.

@TheShed412 are you still experiencing this issue?

[TheShed412]

I will have to try again and see. I haven't used this particular computer with Cinnamon in a couple years.

It took a reinstall of Mint and Cinnamon to fix it when I was experiencing it.

@TheShed412 thanks for the update. If you can update the ticket or close it out if you feel it's corrected, whenever you find the time to test it out would be great. Thanks.

[TheShed412]

I'm installing on an old drive and going to boot to it from my current laptop and see if I can reproduce it. If not I can close it out.

Someone else had a similar issue that commented a few months ago, so it may still be a thing.

I think I am having the same issue on a desktop with 3 external displays,

Power settings do not even show any options for the non-existent lid

I should also add, the reason there is a battery connected is because I have a USB cable attached to my UPS

[Mr-Newlove]

This is strictly for desktops:

So editing: /etc/systemd/logind.conf

Ensuring:

HandleLidSwitch=ignore
LidSwitchIgnoreInhibited=yes

Reboot, and my issue seems to have resolved, at least for now

Edit: After a while it seemed to just start failing again :(
