Touch pad pointer doesn't work

Touch pad pointer didn’t work during install and after install of Zorin 15.3 core essentials but works on windows 10 using same laptop.

@kjleitch Hi and welcome to the forum.
What spec machine are you running Zorin Core 15.3 on?
Is it just the touchpad pointer, or are the touchpad buttons also not working?
You can test using Settings>Mouse and Touchpad see:
