Currently 4.6.0 doesn't work with skylake for me when I plug in a 3440x1440 monitor on a Dell XPS 9550, both with and without xserver- xorg-video-intel installed. It never has worked reliably on any kernel version. Currently, the monitor works maybe 20% of the time - so if you persist for 5 boots you've got a reasonable chance of getting lucky. The only noticeable change from 4.5 to 4.6 is in the kernel backtraces produced - they have got fewer, and they are only warnings now. So from my point of view Intel still hasn't produced a working kernel driver for hardware they released a year ago. I sincerely hope they get the thing stable before we get to stretch, but to date progress has been very slow.
