Hi, I tried to build the system per title and everything worked fine so far. The touch-pad cursor moves with slow acceleration and I cannot click. If I attach an external mouse it works fine though. I went to mouse and touch-pad setting and device name chosen was “ETPS/2 Elantech Touch-pad.”
I believe it depends on which kernel you are using.
See if Synaptics is installed, or libinput. Libinput is pretty much taking over synaptics.
If you have Synaptics installed, try synclient. Read man pages
If libinput, read man pages to know what file to create for X
It all comes down to which kernel and either synaptics or libinput
