I would be happy to do the reverse bisection if there is a call for it, but upon further reflection, perhaps it's just not reasonable to fix this for Trusty, at least not anytime soon. A lot of the hardware in this tablet is *very* new, and trying to support it any time in the near future would probably break something else.

But I can't actually use that kernel either, due to a regression (I guess that will be a separate report). Consider this a suggestion to backport the fix for this to Trusty. When booting the current Trusty kernel, there is no video on the touchscreen. HDMI output works, and even without HDMI connected X is running fine (as evidenced by connecting through x11vnc). And either alternative output method shows that the touchscreen is working fine as an INPUT device. But no picture. Attaching two udev logs, one from booting 3.13.0-32, the other from 3.16.0-6. You can see that in the 3.16 log, quite a few more devices under /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/INT33C3:00/ are discovered compared to the 3.13 -- I'm assuming one of those is the video, since that's where the touchscreen-as-input lives.
