Is there any way to check if it's an upstream bug? There is a bug opened on
kernel bugzilla, but no updates (other than my additional discoveries).
This bug appears to be distro dependent, e.g. doesn't happen on Arch.
I also tried asking around on the forum to try to further isolate the issue,
You're probably thinking about this one:
http://ubuntuforums.org/showthread.php?t=2187204page=8 (2nd to last post).
And you're absolutely right it's the best place for this kind of discussion.

Hi Alex,
Thanks for checking the multitouch. I don't have the keyboard dock. The
only interesting accessory I have is the active pen/stylus, which
frankly I haven't even bothered trying under Linux as I seriously doubt
it would work.
I don't have a link in front of me, but when I was doing some
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
Alex, can you confirm whether multitouch (as opposed to single touch)
works with i386 Ubuntu 14.10? Thank you!
Also, I do plan to submit an upstream bug when I get a chance.

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
Don't know if that helps, but I just tried the i386 version of Ubuntu 14.10.
(published on the 5th of September 2014).
And to my pleasant surprise video and touchscreen are working at the same time!
Cheers, Alex

Bugs,
This issue appears to be an upstream bug, since you tested the latest
upstream kernel. Would it be possible for you to open an upstream bug
report[0]? That will allow the upstream Developers to examine the issue,
and may provide a quicker resolution to the bug.
Please follow the instructions on
Mainline kernel as of today (3.17-rc2-utopic) does not fix this bug.
Logs look about the same as they did on 3.16.0 when I first reported.

** Description changed:
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.

Sorry, should have been more explicit: touchscreen-as-input works fine
in current Trusty kernel (again, see #1354598).
