Hi Steven,

I tried again and I can confirm that it is single touch out of the box with all current i386 Images I tried.
I have no idea how to achieve multi touch (very limited experience with Linux on touch-enabled devices).

On a side note I received the battery-equipped keyboard dock today and it's causing kernel panics
and completely stops working (keys and touchpad) when you push any keyboard key after booting.
As long as you don't push a button the touchpad is working.

Do you experience the same?

Cheers, 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.
