Touchpad cursor jumping erratically

I've recently bought a new Acer TravelMate B115-M, which came with some CLI-only version of Linux Linpus pre-installed. I've tried, besides Arch, Fedora, openSUSE and even OpenBSD. On all the Linux distros the touchpad cursor jumps erratically around the screen, after a few minutes of normal behavior, both under Xorg and under Wayland. With BSD it starts to scroll up and down, so the problem differs (only) slightly on BSD. It only stops when I press the key combination to disable the touchscreen, and then re-enable it. The BIOS also has a option to switch between Basic touchpad mode and Advanced mode. I've noticed that in basic mode the psmouse module is loaded and in advanced mode the i2c_hid module is loaded at bootup. Switching from advanced to basic, or the other way around didn't accomplish anything, the cursor is still dancing when it feels like dancing...
Can anybody help me? Could it be because of the drivers, the kernel, the BIOS or because of the hardware?

Until today we have not found a solution.

It was a hardware problem I had it repaired.
