I previously read about your experience with the X140e,[1] which is "certified pre-install for Ubuntu"[2] rather than "certified for Ubuntu"[3]. (I made note of your previous post in my personal wiki.) It sucks that hardware that is "certified pre-install" can have so many issues with vanilla Ubuntu. I definitely learned from your experience and plan to avoid hardware that is "certified pre-install".
