I have a Lenovo Thinkpad T440 that came with the infamous clackpad. Since that was much of an annoyance, I replaced it with a T540 touchpad - Alps DualPoint TouchPad. Here's the output from
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=11 [slave pointer (2)] ⎜ ↳ DualPoint Stick id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Integrated Camera id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)]
I used to run Windows 8.1 and the touchpad worked just fine with multi-finger gestures as well. However, in elementaryOS, only the two-finger scrolling work. That itself is fine but sometimes (let's say every third or fourth scroll) the scrolling starts off extremely jumpy. If I am trying to go down a page, it'll jump all the way up near the start of the page.
Is this a mouse sensitivity issue, driver issue? How can I fix it?
