zenbook ux302lg intel video driver fails

[Tessa]

Opening this per Bug #1263015.

I'm seeing this issue on a fresh 14.04 install. However, unlike 13.10, using "nomodeset" and the generic SVGA X drivers seem to work enough to start the display at its native resolution.

As you can see, the Intel driver isn't being loaded at all on my ux302lg:

# lshw -c video
  *-display UNCLAIMED

       configuration: latency=0

Using the following intel-drm-next kernel, along with removing "nomodeset" from my boot options, has allowed me to get the intel driver working, like others have reported:

http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/linux-image-3.14.0-997-generic_3.14.0-997.201404170342_amd64.deb

As well, the nvidia card seems to function correctly with bumblebee, even with the intel-drm-next kernel. So hopefully we'll see a backport of a newer kernel with these fixes into 14.04 at some point, perhaps for 14.0.4.1?
