hello! kinda similar to other posts about unchangable tablet orientation. But! Instead of saying “primary (default)”, mine says “not applicable”. I use Kde 6.5.2 on EndeavourOS with Wayland.
i use wacom one M, here’s libinput list-devices command output:

it’s not really a problem for me since my pc since my tablet is already facing the right direction (pc is sitting to my left, so the tablet’s wire is going to the left and everything is good) and i don’t need a ability to change it, but the lack of ability to change it is a bit jarring.
I don’t really know if it’s a bug or a lack of feature, but i hope there’ll be some changes some time soon for it! 
(i don’t really know how to write these kinds of texts, and if the problem i’m talking about already has a solution, don’t be rude.)
