use that number to define the touchpad (I called it ID)
xinput --set-prop "ID" "Synaptics Noise Cancellation" 20 20 and play with the '20 20' at the end like '30 30' or more.
The current setting is '10 10'
Then you can try out the following commands one by one and find out which settings do what you need.
xinput --set-prop "ID" "Synaptics Finger" 35 45 250
xinput --set-prop "ID" "Synaptics Scrolling Distance" 180 180
Once you've found the settings you like the most ....we'll make it stick for next restarts.
BTW, you can see all your current touchpad properties with: xinput list-props "ID"
And before you ask: Yes, the same commands work on Deepin. Where on Deepin you might have a diiferent id number ... so query that first.
Considering this has happened before ..... and both of us fell for the same issue again:
@Thanatermesis should de-activate (uncheck) that option by default.
Not everyone is going to take the trouble to read up on the forum here and may in consequence call Elive (or with luck, only the configurator) total shit and move to another distro.
On top I think the addition of enabling "Palm Detect" would be a bonus....it's disabled by default in the current settings.
