Also tried editing /etc/default/acpi-support and commenting out the line LOCK_SCREEN=true. That did not work.
Just found a workaround that seems to take care of the problem. Install the Gnome Extension: Disable Screen Shield and activate it. The lock screen no longer appears after screen blanking. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1827751 Title: Lock screen displayed after screen blanking even when lock screen disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1827751/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
