One difference between artful and bionic is that bionic has libglvnd0 installed (and libegl1 depends on it, so I can't really remove it). Artful doesn't have it installed. I read in one bug report (for Arch or Fedora? I can't find it now) with similar symptoms (ie no wayland session) that libglvnd was causing problems. Could this issue be related to libglvnd0?
