I know this is not necessarily CachyOS related, but I thought I might be able to get some help here. I have an issue on my Lenovo Laptop where the Lenovo Active Pen 2 under Arch / CachyOS with GNOME on Wayland always recognises the eraser as pressed. While this is probably a libinput issue, I can’t wait for possibly months to get a fix on that side. While I will report this issue to them, I would like to fix the problem intermediately.
This was never a problem under Fedora with GNOME on Wayland. I think the problem might be that libinput on Arch loads the Wacom driver, while Fedora probably just fell back to the generic libinput driver. I got that idea because in GNOME settings my screen now is configurable in the Wacom settings, that never was the case on Fedora.
I stumble across this thread [SOLVED] Weird behavior, button on wacom pen triggering on its own / Kernel & Hardware / Arch Linux Forums however, that is not viable in Wayland any more since there is no config file available for libinput. Is there any way I can force the libinput driver for the “Wacom HID 52C2 Pen” device under Wayland, while GNOME is not specifically exposing this setting?
Edit: Scratch all that, I just tried the live ISO for Fedora 41 and found out it’s not related to Arch. After some trial, it seems like this might actually be an issue with the 6.11 Kernel. After downgrading to 6.10.10 everything works fine again. I guess my new question is now where would I report this? Is this still a libinput or a Kernel upstream issue?
