LapBook Pro - Linux Touchpad not working

Yesterday my new LapBook Pro got delivered and it i’m really happy with it. But since I’m a Linux user I tried to install Linux on it but after the installation the touchpad stopped working (while in the installer the touchpad worked perfectly). I tried several different Linux Distributions by now (Arch, Ubuntu, Mint, PopOS, etc.) and all had that problem. The interesting thing for Linux Mint was however that the touchpad first worked perfect like in the installer and then after I updated the system it stopped working as well. Any ideas hwo to fix that? The touchpad is working well on my Windows partition
