AppImage OSD-KEYBOARD fails in Linux Mint

[jujlguljg]

./appimage osd-keyboard

/tmp/.mount_sc-conVpeBgW/usr/lib/python3.12/site-packages/scc/osd/__init__.py:11: PyGIWarning: Gdk was imported without specifying a version first. Use gi.require_version('Gdk', '3.0') before import to ensure that the right version gets loaded.

Gtk-Message: 21:40:27.961: Failed to load module "xapp-gtk3-module"

ValueError: Namespace GtkLayerShell not available

Gtk-Message: 21:40:27.961: Failed to load module "xapp-gtk3-module"

when trying to sudo apt install libxapp-gtk3-module:

trying to overwrite '/etc/X11/Xsession.d/80xapp-gtk3-module', which is also in package libxapp1:amd64 2.8.8+xia

someone in Mint IRC said libxapp1 has xapp-gtk3-module in it
we verified with:

ls -la /usr/lib/x86_64-linux-gnu/gtk-3.0/modules/libxapp-gtk3-module.so
-rw-r--r-- 1 root root 14328 Jan 6 09:17 /usr/lib/x86_64-linux-gnu/gtk-3.0/modules/libxapp-gtk3-module.so

i think this is because you are packaged for ubuntu and not mint.
mint made xapps iirc and may have messed with something

thats all i can tell you

ValueError: Namespace GtkLayerShell not available
libgtk-layershell0 is installed

Are you using GNOME?

Mutter does not support LayerShell.

I've fixed the warnings in 06973c1 and released 0.5.0 since the beta has been going on for a bit long.

[jujlguljg]

Are you using GNOME?

Xfce.

---

only layer-shell error remains on 0.5.0

0.5.0 still has the layer-shell problem on a fresh Cinnamon and Xfce VM

x11 btw.

here is the traceback
idk

[C0rn3j]

The package with the bindings on Ubuntu 24.04 is gir1.2-gtklayershell-0.1, not sure about Mint.

[0] # python
>>> import gi
>>> gi.require_version("GtkLayerShell", "0.1")

You should be able to import this without errors.

The OSD should work on X11 in all cases, even on Mutter.

The same goes for Nobara 41 (Fedora based) on KDE Plasma. And yes, I had gtk-layer-shell-0.9.0-1.fc41.x86_64 installed. Previous version 0.4.9.8 worked.
