Hello,
I recently installed Antergos on my Acer Aspire E15 and have been having this odd problem with the trackpad in which it acts very jumpy. This happens nearly 100% of the time and also happened on the installation media. This problem persisted even after a reinstall and does/did not happen on my friend’s laptop which was installed off the same installation media. The problem does not happen in windows.

Model number: E5-575G-53VG
Specs:
15.6" Full HD Display
Intel Core i5 6200U
NVIDIA 940MX
8GB DDR4
256GB SSD
256GB HDD (installed post-purchase)
Came Pre-loaded with Windows 10
