Smooth (per-pixel) scrolling unavailable on X230 touchpad

[Jacob Peddicord]

This is the same hardware as in bug 1042069, but is a different issue.

Two-finger and edge scrolling work correctly in both horizontal and vertical directions. However, there doesn't appear to be any smooth/pixel scrolling: scrolling actions still register as "clicks" of the mouse wheel and there don't appear to be any smooth-scrolling axes.

It should be noted that I'm using the workaround in comment #5 in the above bug (copied below), but smooth scrolling is not present without the configuration either. It may just be a detection issue: I haven't booted Windows on this laptop since I purchased it, but per-pixel scrolling did work there, and it worked on my previous laptop with a Synaptics touchpad. Please let me know if you need any extra information.

Status changed to 'Confirmed' because the bug affects multiple users.

[Christopher Barrington-Leigh (cpbl)]

This problem exists in 13.04 too.

[Christopher Barrington-Leigh (cpbl)]

So this problem seems consistent on 12.10, 13.04 and also 13.10.
What can we do to fix it or characterize it better?

[Christopher Barrington-Leigh (cpbl)]

@jpeddicord: I do not see a copy of the workaround for this in your original report. I also cannot find it in the link you give to another bug. That workaround seems to address the cursor movement problem, but not the two-finger scrolling problem. Would you be able to report what, exactly, you did?

Jacob Peddicord, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-input-synaptics REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
