Comment 2 Nate Graham 2025-05-27 21:46:59 UTC

See https://artonwayland.redstrate.com, under "Why isn't my tablet supported? Nothing useful shows up under the KCM."

This needs to be fixed upstream, possibly in Libinput, but perhaps even in the kernel driver, ideally by the manufacturer.

Comment 3 Joshua Goins 2025-05-28 05:20:30 UTC

Nate is correct, but to be more specific it will only work in the KCM only when libinput considers it a tablet-pad (that would show up under capaibility instead of "keyboard") It would also display the buttons, and so on:

> Pad:
>    Rings:   0
>    Strips:  0
>    Dials:   2
>    Buttons: 4
>    Mode groups: 1
>        Group 0:
>            Modes: 1
>            Buttons: 0, 1, 2, 3
>            Dials: 0, 1
