I have a problem with the Dell Adapter DA200 with my Dell XPS 13. The OS is Ubuntu 16.04, kernel 4.15.0. I installed the patch for i915 usbc (https://bugs.freedesktop.org/show_bug.cgi?id=93578&dgc=SM&cid=60904&lid=730074515&linkId=32430080) and it worked until last week. For the module i915-usbc, I used kernel 4.10.0, but now it doesn't work. I see the monitor in HDMI but there is no video.
Maybe the problem is that the adapter now doesn't work? What is the best usbc adapter to work with Ubuntu 16.04 or 18.04 for HDMI and VGA?
