Bug Description

After upgrading my middle click doesn't work. I have a Lenovo Ideapad s10-3t which has a tiny touchpad. I used to press the middle area of the lower edge to get a middle click, to, i.e. close Firefox tabs, open links in new tabs and most importantly: Use the cut buffer to copy and paste.

I've read https://help.ubuntu.com/12.04/ubuntu-help/mouse-middleclick.html and it recommends three finger tapping (I can't change that behaviour anyway, can I? The mouse settings dialouge doesn't allow me specify whether I want to have three finger tapping for middle click). Anyway, according to xinput, my touchpad only recognises two fingers:

So there seems to be a bug in Ubuntu forcing me to use three finger tap altough I can't do it.

I can get my behaviour back by doing "synclinent EmulateMidButtonTime=75".

I expected Ubuntu to not have that regression in first place, then a way to tell Ubuntu whether I want (or can) use three finger tap and then activate that option mentioned above automatically if I only have a two finger touchpad.

FWIW: Here is my synclient output:

Funny that it reports "triple".

Muelli, 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 xorg REPLACE-WITH-BUG-NUMBER

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.
