Problem: my cursor jumps and clicks everywhere, and it has become more severe - it is maddening :'(
This question I have seen before in forums and tried their suggestions, but I still have this problem.
What I tried:
- I found a possible solution: lowering KDE Plasma's sensitivity, but this dialogue window was gray colored.
- Then I found the reason and solution for this graying: it was libinput. Here are the links I read: https://www.reddit.com/r/kde/comments/d21mwv/why_are_my_touchpad_sensitivity_settings_greyed/ and https://forum.kde.org/viewtopic.php?t=130072 - see coryw Thu Mar 21. But removing libinput makes my keyboard non-functional.
Now: I do not know what I can do.
System: Arch-linux for Surface Pro 4 and KDE up to date.
Best and thank you in advance,
Roberto
I FOUND THE SOLUTION!: disable touch screen instead of touchpad, see:
Mouse cursor jumping around the screen and clicking on HP Pavilion x360
This information tells you how to disable touch screens for Arch Linux:

I hope others will solve this problem of a jumping cursor!
