cagara, 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
I believe I have the issue described in comment #15 for the X230, on my
Lenovo IdeaPad Z710.
With a steady finger drag the cursor will move very slightly for a
couple pixels before quickly shifting forward a couple pixels, such that
at first I believed that the cursor was merely snapping to each
After more time with it, it appears the issue still appears with an
acceleration profile of 4 although less noticeably.
