Problem: If I rest one fingertip on my touchpad and do NOT move it, the cursor will jump in vertical direction up and down.
I have a Lenovo Yoga 13, i5, 8GB Ram, 128 GB SSD
BIOS: latest version Rev 55
This problem occurs in both operating systems, but not always. Cleaning the Touchpad does not have an influence. If I rest my fingertip on the touchpad and do not move it, the cursor will keeping jumping up and down with mainly small but rarely high altitudes. This behavior is illustrated in this Youtube Video which I recorded in Ubuntu. If the cursor disappears from the recorded area, a huge leap was performed and I have to move the cursor into scope again.
Already tried without success:
This problem really drives me nuts Working becomes a really frustrating job, cause you will hit wrong buttons very often...
Looking forward to your help!

it only happens when you touch the touchpad? I understood it happened when you did not....
If it happens only when you touch the touch pad, decrease the sensitivity of the trackpad and check "increase pointer accuracy".
