I recently updated to 20.04 LTS and I've been having some trouble with lock screen. When I close the lid it is configured to suspend and lock and the suspend part is ok but when I open the lid, most of the time it is unlocked by itself without asking for password. And also sometimes it works and asks for password just completely random.
I changed logind.conf but didn't help:


And I'm using GNOME.

  • check in StartupApplications if there is something called ignore-lid-switch-tweak and report back

  • @kannzzmm2 No there's only im-launch, NVIDIA X Server Settings, SSH Key Agent and a couple more non related programs. Also suspend when laptop lid is closed is turned on in tweaks. Commented Jun 20, 2020 at 9:18

So I disabled "Extensions" in Tweaks and it got fixed. I turned Extensions on and seems like everything's fine and the lock screen is fixed. It was probably a bug with an extension and it got removed as I switched it off and on.


Cyb3r4dd1ct's advice worked out for me. However I decided to figure out what exact extension was causing the problem, and Gtile was the culprit.

Edited: It's apparently a known issue gnome-shell 3.36 crashing on screen lock/unlock. You need to upgrade gnome-shell to at least 3.36.3-1:

$ gnome-shell --version
$ sudo apt-get update
$ sudo apt-get upgrade gnome-shell
