We only counted configured monitors and whether the config was applicable (could be assigned), howeverwe didn't include disabled monitors when comparing. This could caused incorrect configurations to be applied when trying to use the previous configuration. One scenario where this happened was one a system with one laptop screen and one external monitor that was hot plugged some point after start up. When the laptop lid was closed, the 'previous configuration' being the configuration where only the laptop panel was enabled, passed 'is-complete' check as the number of configured monitors were correct, and the configuration was applicable. Avoid this issue by simply comparing the configuration key of the previous configuration and the configuration key of the current state. This correctly identifies a laptop panel with the lid closed as inaccessible, thus doesn't incorrectly revert to the previous configuration. https://bugzilla.gnome.org/show_bug.cgi?id=788915
