    GnomeRR: force the DPMS mode change to mutter always
    
    Our cached DPMS mode value can be wrong in face of changes by
    other clients we haven't seen yet, so always send the change
    to mutter, and let it optimize away if needed (in practice,
    it should never optimize, because the only reliable source
    of DPMS state is the kernel driver, and several API calls
    can reset DPMS without any change notification)
