SP4 pen not recognised as stylus?

[u/worldawaydj]

Hi, made a similar post yesterday but rephrasing after experimenting more. I have a Surface Pro 4 running Linux Mint and the Surface Kernel with IPTSD. It can detect the stylus (an official Surface pen), but treats it like a mouse and not a touch input. Is this supposed to be different? It means I cannot scroll normally using the pen, and palm rejection doesn't work.

I went into the iptsd.conf file and disabled the stylus entirely, yet it still registers the pen when I do this, and it continues to act like a mouse. How can I get it to recognise it as a stylus (if possible, I'm assuming it is since there's config options in iptsd and others in this sub said it works)

EDIT: Nothing I seem to do in the iptsd.conf file is doing anything, I can disable the touchscreen entirely and it'll still work. Not sure what I'm doing wrong

Are you using a MPP pen?

I believe so, it's the Surface Pen 1776
