I just bought the new Dell XPS 9360.
I've had two main issues after installing latest Ubuntu:
- touchpad config, which I fixed thanks to this post
- wifi being reallllllly slow, not all the time, not on every wifi, but too often. Most of the time it starts by working reasonably, until falling down to super slowness interrupted by temporary disconnections...
