You could check with powertop. If you're measuring (e.g. via ssh from
another system) when the system is inactive, it might be that the video
driver for X turns the video card into a power-saving mode when it's
idle, and the console driver isn't doing that.
Are you including the display in your measurement? How exactly are you
