I can confirm this behavior on a fresh install of 16.04 on the Dell XPS 13 developer edition. I get the same error message when trying to setup a wireless connection in lightdm. I don't whether this connected or not but the hotkeys (volume up/down, screen brightness) also don't work in lightdm. I installed kernel 4.6 because of the wireless toggle not working in 4.4. That solved the wireless toggle but did not change the issue in lightdm.
