Gnome 3.14: Is possible to disable the lock screen?

I want to disable the lock screen on Gnome 3.14 after the computer is woken up from suspension. I've tried different proposed solutions, like this one, but they does now work.

Disable with

gsettings set org.gnome.desktop.screensaver ubuntu-lock-on-suspend false

Enable with

gsettings set org.gnome.desktop.screensaver ubuntu-lock-on-suspend true

Or reset to the default value false with

gsettings reset org.gnome.desktop.screensaver ubuntu-lock-on-suspend

Graphically, use dconf Editor to flip the status of org.gnome.desktop.screensaver ubuntu-lock-on-suspend from checked to un-checked
