Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during
any development cycle it is impossible for us to review them all.
Therefore, we occasionally resort to using automated bots to request
further testing. This is
Val, the next step would be to commit bisect the mainline kernel
following
https://wiki.ubuntu.com/Kernel/KernelBisection#Commit_bisecting_upstream_kernel_versions
. It would be best to expand your commit bisection a little past 3.2,
and little before 3.1.5.

Val, getting back to your comment
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1260513/comments/23 ,
could you please clarify:
1) The latest mainline kernel for Oneiric version specifically that didn't
reproduce the bug?
2) The earliest mainline kernel for Precise version specifically
Christopher, to answer your questions:
1) The latest mainline kernel for Oneiric that did not reproduce the bug:
3.2.0-030200rc4 (201112012035).
2) The earliest mainline kernel for Precise that did reproduce the bug:
3.1.5-030105 (20111209125).
This info is in post #18 above:
Christopher, I have tested v.3.14-rc7 which is now the latest mainline
kernel:
val@vk2011:~$ uname -a
Linux vk2011 3.14.0-031400rc7-generic #201403162235 SMP Mon Mar 17 02:36:19 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux
The result is the same as in prior tests: the horizontal scrolling is
broken.
Val, what you can do is test the latest mainline kernel, as previously
requested. However, the latest one available now is
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc6-trusty/ .

Christopher, unless I do something this bug is going to expire in a
couple of weeks. I don't want it to expire into a mass grave of orphaned
bugs. I've invested a significant number of hours investigating it, all
in the hope that my work won't be wasted, all in an attempt to make
Ubuntu more
Christopher, as I wrote in post #18 above the horizontal scrolling works
fine in the last mainline kernel for Oneiric and it is broken in the
first mainline kernel for Precise, chronologically speaking.
Horizontal scrolling works fine in every mainline kernel for Oneiric
that I tested, and it is
Val, one thing that would be helpful would be to not jump around
distributions, as they don't share the same userspace. As you noted
previously, a WORKAROUND in userspace fixed this problem. So, if you are
going to test different mainline kernels in Precise, stay with this.
In addition to this,
Christopher, do you have any suggestions as to what I should try next? I
am still confused, and I do not understand why my test results on
Precise are different from Oneric where the same kernel version is used
in both installs.

You received this bug notification because you are a member of
Christopher, I am a bit stumped. What I am getting does not make much
sense.
Test 1: 11.10 Oneiric, mainline kernel 3.2.0-030200rc4 (201112012035). This is
the last mainline kernel for Oneiric from
http://kernel.ubuntu.com/~kernel-ppa/mainline/.
Test Result: horizontal scrolling works properly.
Val, you would be experiencing a regression/fix/regression scenario. It
was broken in a prior release, fixed in a newer one, and then it broke
again.
Given that you know 3.2.0-030200rc4 (201112012035) works, you would want
to find the next kernel that it fails on after this kernel version (ex.
Christopher, this time I tested 3.2.0-030200rc4 for Oneiric and
3.2.0-030200rc4 for Precise. Both were taken from the kernel-ppa and
installed in Oneiric and Precise correspondingly.
Oneiric, 3.2.0-030200rc4: all is well.
Precise, 3.2.0-030200rc4: USB mouse is not detected properly and
This seems like it should be fixed by adding a workaround in the kernel,
not a hack in userspace evdev.

additional upstream developers to examine the issue. Once you've tested the

Val, thank you for performing the requested tests. Did this problem not
occur in a release prior to Trusty?

Christopher, as I noted in my initial submission this bug is a sequel to
LP bug #926917 and the problem has persisted with every Ubuntu release
since 12.04. That information was unfortunately edited out from my
initial submission. This bug was created on your request because the

Val, to clarify:
1) This problem is reproducible in as early as 12.04.1?
2) Was it not reproducible in a release prior to this?

Christopher, this problem did not exist prior to 12.04. It seems to be a
regression in 12.04. I have been using the same mouse+keyboard combo
since 8.04 or so, and it is only in 12.04 that my mouse tilt (horizontal
scrolling) got broken.

Val, the next step is to fully commit bisect from a pre-Precise release
to Precise, in order to identify the offending commit. Could you please
do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Christopher, can you tell if trying all these different kernels can be
done in a guest OS in Virtualbox? To identify the offending commit I
will need to do quite a few reboots. Doing such reboots on my main
workstation means a lot of time would be wasted to idling while my
computer reboots. I
Val, unfortunately, a virtual machine would not be an acceptable testing
environment, as this a host hardware dependent problem.
As well, the bisect would want to be done without any WORKAROUNDs
involved.
