Comment 2 for bug 209532

Please note that if "Disable sticky keys if two keys are pressed together", this is NOT changed in the Configuration Editor>desktop>gnome>accessibility>keyboard>"stickykeys_two_key_off" check box.

This is constantly reset (i.e. ticked) either by booting or something else. It is not possible to determine exactly when it gets reset as one does not know until after the event.
