[Bug 1354604] Re: Regression: touchscreen-as-input not recognized in recent kernels (Dell Venue 11 Pro 7130)
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.17 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.

Title:
Regression: touchscreen-as-input not recognized in recent kernels
(Dell Venue 11 Pro 7130)
Status in “linux” package in Ubuntu:
Incomplete
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.
