Sorry for the double post. So I did my research and I found the kernel patches that manjaro has applied to provide support for the i2c type devices that directly address issues for several machines along with Teclast F6 Pro and Teclast F7.
Manjaro 18’s running kernel is 4.19 patched. I downloaded the 4.20 kernel sources and queried the patched files to see if they have been updated or not and it seems that they are indeed patched! So hopefully kernel 4.20 will solve the touchpad issues along all distributions. Also, a testing version of 4.20 made it yesterday on Arch testing repository so hopefully in the upcoming days i’ll be able to verify if issues are resolved or not.
EDIT: I am so dumb I didn’t think that I could already test the package. ALL GOOD. Touchpad works like a charm in 4.20 so issue is resolved.
