Adjust trackpad speed

Hey guys, I have an Acer Aspire 5742 and running Leap 15.
I can’t seem to adjust my trackpad sensitivity/speed. I’ve tried with the mouse tool applications but no change.
It’s quite slow to move around the screen, and oddly when I was previously running 12.3 it was very fast but I had never tried adjusting it then.

I’ve installed and tried just about every application I could find but no luck in adjusting speed. I haven’t tried using a USB mouse to see if the settings would work for that.

Thanks.

Solved somehow finally came across synaptic application.
