However upon resume I get a checkerboard style page rather than the lightdm login page. If I disable the nvidia stuff from the optimus box and just have the intel gfx running suspend and resume work again. Please note that the issue only seems to happen when the nvidia discreet gfx card is in use. If the device is switched to intel only then it doesn't.
