I just installed ubuntu on my thinkpad-x220 and my touchpad is extremely jittery / jumpy. If I don’t touch it my mouse stays still which is fine, but once I start moving my finger on the touchpad the mouse shakes and moves which is so annoying.
Apparently this is a well known issue, but I’m not having any luck using the recomended solution of xinput: http://x220.mcdonnelltech.com/ubuntu/#touchpad
When I run xinput I see this:
root@martin-ThinkPad-X220:~# xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint 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: Integrated C id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)]
I run this command:
xinput --set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Noise Cancellation" 20 20
but get an error message saying:
root@martin-ThinkPad-X220:~# xinput --set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Noise Cancellation" 20 20 property 'Synaptics Noise Cancellation' doesn't exist, you need to specify its type and format
