[Lenovo ThinkPad T440s] Mouse wheel emulation non-functional with soft buttons

[ltmon]

When using a Lenovo T440S wheel emulation does not work. Wheel emulation is functional when not using a hot button, but attempting to enable it when holding down middle button does not work.

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

ltmon, 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 xorg 1268049

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information. As well, 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.
