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 line of text. The settings in comment i#15 are a fix because the problem does not occur with the AccelerationProfile set to 2, but it is imperfect because I prefer the other acceleration profile. Changing only the acceleration profile to 4 and the constant deceleration to 3 also works, depending on how you like your cursor. It is difficult to tell which other acceleration profiles have the problem, but it may also occur in 3. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1042069 Title: Jumpy Mouse Cursor using Thinkpad X230 (+X230t) Touchpad To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1042069/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
