It seems to me that many people are reporting instability issues for Ubuntu 16.10 using the latest 1.2.65 driver. Severe instabilities occur for certain types of hardware that was supported in Ubuntu 16.04.

I have a Dell XPS 13 (9343) and DL-3100. The screen keeps disappearing and re-appearing. It happens really randomly and sometimes many times per minute, other times it might be once per 20 minute. The displays go to black and everything crashes. It crashes often, but not always. This makes the applications stuck to that display crash as well. It is very poor performance (lag/hanging/high CPU usage) and not possible anything else than very low resolution. The poor performance and high CPU usage is a constant problem, but it gets worse right before and right after the crash (system almost hangs/freeze).

The setup worked flawlessly in Ubuntu 14.04 (no problems). This is also a "clean install" of Ubuntu 16.10. Hope you could fix this in the next release!
