Seems like you're right, François. I installed Powertop on both Ubuntu 18.04 (~12.5W at idle) and Fedora 27 (~5W) on the same laptop to measure the power comsumption. The method is not what I'd call scientific, but the difference is big enough to tell there's indeed something wrong. On Fedora, I installed the proprietary driver via RPM Fusion, and disabled it with "modprobe.blacklist=nvidia,nvidia_drm,nvidia_modeset,nvidia_uvm" kernel parameter.
