Hello, I’m having an issue with my XP-Pen Deco 01 V2 tablet on Manjaro Linux.
The problem is that the side button on the pen, which should act as right-click (BTN_RIGHT), does not work in my X11 session.
What I’ve tried so far:
Tested the device on Wayland: the right-click button works correctly there, but unfortunately Wayland is unstable on my system (random freezes and graphical glitches), so I need to stay on X11.
Checked raw input events with libinput debug-events → the button does emit a BTN_RIGHT pressed signal.
Verified the device with xinput list and xinput list-props → it shows up as “XP-Pen Pen stylus” with Wacom properties.
Tried remapping the buttons with:
xinput set-button-map → no effect.
xsetwacom set "XP-Pen Pen stylus" Button 2 "button 3" (also tried Button 3, Button All) → no effect.
Installed and tested input-remapper to intercept BTN_RIGHT and map it to button 3 → the tool detects the device, but the button does not generate any usable event under X11 (even though it appears in libinput logs).
Summary:
On Wayland the button works fine.
On X11, BTN_RIGHT is detected at the kernel/libinput level, but neither xsetwacom, xinput, nor input-remapper can map it to a usable right-click.
This seems to be a driver issue with Wacom/libinput on X11 when handling this XP-Pen model.
Question:
Is there a way to properly map this pen button under X11, or is Wayland the only option?
Are there any patches, configuration tweaks, or XP-Pen-specific drivers available for Arch/Manjaro that could fix this?
