Please note that on some notebooks (e.g. ACER 3820 TG) the ON thingy does change the muxes when called with a switched off discrete card. This results in a black screen which can be "repaired" by calling MIGD to change the mux to the desired integrated card. See my bug for a sleep.d script which takes this into account: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1077675
