I'm on Ubuntu 16.10 and using an HP Pavillion 17f and it freaked me out at first, but now its annoying. I had set my down, the top was leaning back, and the screen flipped upside-down; I picked it up and leveled it, tried xrand -o commands, but the screen stayed the same. I rotated my laptop to it's side and the screen re-oriented itself, next I leveled it then tilted it towards me and it fixed itself. I often like using my laptop angled back a couple degrees and the on-by-default unconfigurable auto-rotating screen is really bothering me.
On 16.04 it didn't have that behavior and the https://wiki.ubuntu.com/YakketyYak/ReleaseNotes didn't say it would do that. Also after I upgraded to 16.10, there was a new intel-microcode driver that was available that I installed.
