When I click apply under display settings

  GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.SettingsDaemon.XRANDR_2' on object at path /org/gnome/SettingsDaemon/XRANDR

 could be caused by a conflict between Cinnamon and Gnome?

Description: Ubuntu 12.04.3 LTS
Release: 12.04

gnome-settings-daemon
Version: 3.4.2-0ubuntu0.6.4

I expected the screen resolution to change to the newly selected one, instead I get the error.
Hope this helps.
