I can confirm that I see the same behavior on my Dell Venue Pro 11
(Model 7130).

Every version of Ubuntu 14.04. (that I tried) boots into a black screen on the tablet 
whereas the daily snapshot of 14.10. boots into a working screen, but doesn't have a 
working touchscreen (no response to taps at all, but usable with an external keyboard).

I didn't get the chance to test touch input using the 14.04. versions of Ubuntu since I'm waiting 
for an adapter to hook up the tablet to an external monitor.

I can also confirm that the August snapshot of Kubuntu Active has the screen and the touch 
input working (single touch as far as I can see).

Best, Alex

Title:
  Regression: touchscreen-as-input not recognized in recent kernels
  (Dell Venue 11 Pro 7130)

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Due to bug #1354598, my Dell Venue 11 Pro 7130 tablet is unusable as a
  tablet with the current Trusty kernel, so I have been attempting to
  find a more recent kernel for which the screen functions both as a
  display and a touch input device. No luck so far.

  (Well, actually, oddly enough, that's not quite true: I installed the
  05-Aug-2014 01:21 daily live CD of Kubuntu Active, which is i386 only,
  and *that* worked just fine, from a kernel/hardware perspective. But
  I'm hoping to get an amd64 kernel working.)

  When booting either of the most recent Utopic kernel (3.16.0-6) and
  the kernel team's latest build of upstream (3.16.0-031600), the
  touchscreen is unresponsive to touch input, and inspection of the logs
  confirms that the multitouch device is not recognized as such.

  Will run apport-collect. Also the udev logs attached to bug #1354598
  may be interesting.
