blanking locks screen although screen lock is disabled

[Jurgen Schellaert]

I disabled screen lock from Settings > Privacy > Screen. Even so, I am forced to log in any time my screen has blanked.

When I inspect dconf-editor (org.gnome.desktop.lockdown), I see that locking is indeed active.

This looks like a discrepancy between the settings mechanism and dconf.

Assuming the screen is really locked then this bug is the responsibility of gnome-shell.

Although if gnome-shell crashed when the screen blanked then you might be returned to the login screen.

Which is it? Can you provide a photo of the lock screen?

Possibly related to bug #1968208, which I reported today: frozen gnome-shell after logging in/unlocking.

This new bug would indicate that gnome-shell indeed randomly crashes. The behaviour is inconsistent, though. Sometimes it does not crash at all, at other times it does but it does not always cause the desktop to freeze.

I can add a photo, as your requested, but I wonder whether that would add anything. The lock screen is simply the log-in screen that traditionally comes up when the system is booted.

Update: this gnome-shell crash appears to be related chiefly to the flatpak firefox I am using. It is rare for other applications to freeze.

Running gsettings with sudo seems to nail it:
sudo gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'

But this disables screen locking for every user. That is irrelevant to me but some may care.

The lock screen and login screen are different, which is why I asked. If you see the login screen instead of the lock screen then gnome-shell has crashed. So maybe this is just bug 1968208 (which is bug 1965897).
