Bug Description

I'm running Ubuntu Gnome 16.10:
 lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.10
Release: 16.10
Codename: yakkety

With:
gnome-shell --version
GNOME Shell 3.20.4

I am running GDM.

I set the privacy setting to Automatic Screen lock as on and the time to 30 seconds.
The screen never locks.

I do have the gnome extension that uses a button to lock the screen, that works fine. Super-L does NOT work for some reason, but the key code is set under Keyboard->System->lock screen.

running - gnome-screensaver-command -l - in terminal will lock the screen.

I work in a HIPAA environment where a screen lock must activate automatically.

Note that bug 49579 means time-based locking is inherently trouble. If you accidentally leave a menu item selected or a virtual machine window open (using a client that captures the keyboard or mouse) then the time-lock won't happen anyway, regardless of whatever bug this is.

We're working on the Mir display server to address this issue. Others are working on the Wayland display server. Hopefully we'll have a solution to this decades-old problem eventually.

THanks

Confirmed on artful (Wayland, with lightdm). The screen never blanks and never locks, despite being configured for 5 minutes.

Daniel, I can't duplicate this bug with Ubuntu 17.10 "Artful" with gnome-shell installed with the GNOME (on X) session using LightDM.

But I can with GNOME on Wayland.

But I can't duplicate this issue with Ubuntu GNOME 17.04 with GNOME on Wayland on GDM. Daniel, could you please report a separate bug then since this does not look to me like the same bug that was originally reported.
