Issue Description

I am encountering an issue where my HUION Huion Tablet_H430P pen tablet is not functional within the Excalidraw plugin in Obsidian when running on Wayland. Specifically, I am unable to select or draw anything using the pen of my pen tablet within the Excalidraw plugin. However, I am able to use the mouse without any issues. Notably, this issue started occurring after 23rd July 2024, and the pen tablet was functioning correctly in Obsidian prior to this date.

Steps to Reproduce

Install Obsidian via Flatpak on Fedora Unix Linux with Hyprland (Wayland) as the window manager.
Open Obsidian and enable the Excalidraw plugin.
Attempt to use the HUION Huion Tablet_H430P pen tablet within the Excalidraw plugin.

Expected Behavior

I expect to be able to use my pen tablet to draw and interact with elements within the Excalidraw plugin, similar to how it functions with a mouse.

Observed Behavior

The pen tablet is not responsive within the Excalidraw plugin. I am unable to select or draw anything using the pen. However, the pen tablet works correctly in other applications and even in standalone Excalidraw instances outside of Obsidian.

Debugging and Troubleshooting Attempts:

Verified that the pen tablet works correctly in other applications and standalone Excalidraw.
Ensured all necessary drivers for the pen tablet are installed and up to date.
Attempted to run Obsidian with the QT_QPA_PLATFORM=xcb environment variable to force X11 compatibility: flatpak run --env=QT_QPA_PLATFORM=xcb md.obsidian.Obsidian This did not resolve the issue.
Verified permissions for Flatpak to access input devices: flatpak override md.obsidian.Obsidian --device=all --filesystem=home
Changed desktop environment from Hyprland to GNOME, but the issue persists in GNOME as well.
Checked system logs and libinput events to ensure the pen tablet is recognized and functioning correctly: sudo libinput debug-events

I would appreciate any guidance or assistance in resolving this issue, as the pen tablet functionality is crucial for my workflow within Obsidian and Excalidraw. Thank you for your support.

are you using Excalidraw in a popout window in Obsidian or within the main workspace?

zsviczian commented 3 months ago

I've tried this on my Huion tablet on Windows 11. I am unable to reproduce the issue... however, if you are experiencing this in a popout window, then 2.2.13-1 beta might resolve the problem for you. You can install 2.2.13-1 beta using BRAT. I have a how-to video here: https://discord.com/channels/1026825302900494357/1076960836901417092/1076964066012184610

I am using it within the Main Workspace

I am happy to report that i have found a workaround for this bug i encountered and here are the steps we can follow

Downgrade the Kernel: Downgrade the kernel version to anything below 6.9.12-200.fc40.x86_64 ( I am personally on the kernel version 6.9.11-200.fc40.x86_64)

Note: Unfortunately This'll not work for wayland and only the x-11-windowing system via the gnome desktop environment

I seem to have the same or similar issue. For me it does not work with many electron apps, so not obsidian-excalidraw specific, but also signal and webcord (discord client) do not work with pen input.
