Binding <key> failed

[arun-mani-j]

Hi there.
I made my app which uses this package and it worked fine in Cinnamon. But I recently shifted to GNOME 3 and whatever key I try to bind, it simply tells me "Binding <my key> failed". I thought that this issue was with my app and so used the example provided by this repository and it also gives me the same error.
Using : Python 3
Keybinder : 3.0
OS : Debian Buster

• It works fine if I use GNOME Classic and Cinnamon instead of GNOME 3

Same problem here yktoo/indicator-sound-switcher#125

Ubuntu Xorg & Cinnamon => Works
Ubuntu Wayland => Doesnt work

edit: it works on Wayland if the app is launched with env GDK_BACKEND=X11 ./myapp. @arun-mani-j you may try this.

This library is forever tied to X11.

There is no generic Wayland solution for global keybindings yet. But I would expect it to happen eventually.

@TingPing is it discussed anywhere in Wayland space, do you know?

I mean... Are wayland devs even aware there's a need for this?

You can track it here: flatpak/xdg-desktop-portal#711

Thanks :)
A short flashback 😴
I actually opened the issue when I was working on my school project of a launcher app. After asking in GNOME Discourse, I learnt about Wayland and X11 for the first time (I started using GNU/Linux that year only approximately).

Though one quick solution (temporary fix till the XDG standards launches) I found is to ask users to create a custom shortcut via their Desktop Environment itself.
