I have spent a lot of time googling and testing on this issue with dCore-xenial and Xorg with an Intel video card.

This is another case where missing dependencies should on my part be the first and simple assumption until proven otherwise.  The Intel Xorg driver is not brought in by importing xorg-all, it seems to be dropped as a dep of xserver-xorg-video-all in Ubuntu.  Import xserver-xorg-video-intel and all should work, using it now.  The xserver-xorg-video-all dep file have been adjusted, I have place all known video drivers in the deps of xserver-xorg-video-all so they will be there regardless.

Ubuntu dropped/demoted the Intel driver in recent releases because they don't think it receives enough support.
The only barriers that can stop you are the ones you create yourself.

I have found on dCore-yakkety if the i915 module is blacklisted then it will be loaded during an X session and X will work.  But on dCore-xenial X will start but the mouse and keyboard are frozen requiring a hard reset.

Thanks for the info on Intel being dropped or demoted in Ubuntu.  On a Ubuntu Yakkety hard drive install, Xorg will not work at all, just a black screen and the i915 video card is the only available chipset I have for both my machines.  Releases of Ubuntu earlier than Xenial worked fine with the i915 kernel driver.  Given the status of Intel video in Ubuntu and the fact in current Ubuntu proper Xorg will not work at least not configless on my machine, I can't support it and recommend using a different video card.

Did you try using the xf86-video-modesetting driver?

Depending on how recent the xorg-server is, the modesetting driver might be part of that package.

Thanks, the modesetting driver is part of the main Xorg package now.

Without the i915 module installed, unaccelerated Xorg works fine unaccelerated with or without xserver-xorg-video-intel. 

I built Wily's release of xserver-xorg-video-intel on dCore-xenial, though that did not make a difference.  I see that a new file exists in Xenial and Yakkety - /usr/lib/xorg/Xorg - that needs to be copied as a real file to the filesystem and then made suid root.  Or else Xorg will start and the desktop visible but be at a hard freeze unresponsive to keyboard or mouse.  I have adjusted the needed startup script for the package xserver-xorg-core and re-importing and SCEs that contain xserver-xorg-core should let intel video work with graphics-4.2.9-tinycore installed as well as xserver-xorg-video-intel.  I will be able to test it tonight for myself, but it should just work.
