Hi,
occasionally the touchpad goes crazy and the cursor starts jumping and even clicking. I have an Aspire V15 Nitro VN7, KDE and libinput is installed. The jumping was worse a couple of months ago.
It can usually be fixed for some time by disabling and enabling the touchpad by the laptop keys.
So I looked into xinput, but I'm not sure where to continue to do something about it

It was a guess that I could something here, but I do not even see relevant values.
What to do?
