Hello

I had this configured to work as I wanted in Mint 18.3 but I don't remember how I did it and am having a hard time figuring it out.

What I want is to disable the feature where the screen locks when my laptop's lid is closed.

It's fine if the screen turns off but I don't want the laptop to sleep or to lock the screen, requiring me to type in a password.

I went to the screensaver settings and set the "Delay before starting screensaver" to never, which I hope means it will never start but I don't know.

I also turned off the "Lock the computer after the screensaver starts" option, though I would like the screensaver to never start.

Under "Power management" both dropdowns for "when lid is closed" are set to "do nothing".

Can someone please help me figure this out?

Thanks in advance.

I have the same problem and it is annoying. If power management is set to suspend and you open laptop no password needed so I assume this is a bug but not sure how to articulate it.

I have exactly the same problem. On LM 19, all updates applied (and home partition encrypted), after the lid is closed, the screen is locked. I use exactly the same settings as in LM 18.3 and the screen was not locked here.

This is really bugging me as well. The power management option says "Do Nothing" when lid is closed. That is inaccurate. It does something when the lid is closed: it activates the lock screen.

edit - this is on version 18.2, so it's not something new in 19 as far as I can tell.

Same here. In 17.3 there was a setting under screensaver to "lock the computer when the screen turns off". That switch is missing in Mint 19.

Has anyone found a solution yet? I'm pretty sure it's the screensaver that turns on, but I don't know how to get stop it.

I can chmod 0 /usr/bin/cinnamon-screensaver and that keeps it from locking when the lid is closed, but that also prevents it from locking when the laptop is suspended.

Good find zacktheperson.... there was one fix suggested on there that I hadn't tried and hey presto it works...

sudoedit /etc/UPower/UPower.conf

Change IgnoreLid=false to IgnoreLid=true, Ctrl-X and then Y and enter to save. Reboot.

This has a side effect of removing Lid Actions entirely from the Power Manager GUI, but also kills the bug of the screensaver kicking in despite settings on lid close. Screensaver remains operational otherwise.

Reverting the edit and rebooting restores the Options in Power manager GUI as-well as the bug...

Thanks guys!

To clarify for others who might run into this problem, this is what I had to do:

* Edit /etc/UPower/UPower.conf and change the IgnoreLid to true: * Then edit /etc/systemd/logind.conf, uncomment the HandleLidSwitch and change it to ignore: * Then reboot.

The screen still turns black when the lid is closed (must be a hardware thing) and if I suspend the machine manually it will still resume when I open the lid. But it will not sleep or turn on the screensaver when I close the lid.

Too bad the UI for this doesn't work, but at least there is this workaround!

Thanks for this post, everyone.

I've been having trouble with my system freezing and suspect it has something to do with the lock screen. I don't know if the freezing issue is fixed, but I was trying to disable the lock screen everywhere so I was going crazy when I couldn't disable lock after lid close. I appreciate the help from you all!

it looks like i need this fix too - can you dumb down the instructions to fix? what do you mean by edit? thanks.

this worked! Running LM19 cinnamon on an old laptop and main issue has been computer locks up completely every time lid is lowered too far, editing both files as @andrewsmith suggests solved it for me, thanks for both question and answer good Sir!

When I made the changes recommended here the screen doesn't lock but when connecting the computer to another screen and closing it I don't see the same as in the computer. Before updating to LM 19 I could close the lid and let the computer working and when I connected it to another screen and closed the lid I could see the same that I had open.

I believe it is fixed now. It is working fine now for me. Nothing done on my part, other than applying all the updates.

This worked also in Peppermint 10! Thanks!
