Any further backports would be gratefully received -- it looks like there's been a fair number of i915 and skylake-related commits recently.

They seem to be due to intel DRM issues, linked to this error: https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/1568865? comments= all

Details in comments on the ticket, but I'm not the only one, and issues include:
- Laptop screen goes black when mouse moves into it, after hotplugging HDMI
- Blank screen on boot and/or resume with external screen plugged in
