Can't open on X11 when a custom xkb layout is being used

[camargomau]

Hello! I'm using Ubuntu 22.10 with GNOME 43.1 running on X11.

When I try to open ZapZap, I get this error that's preventing it from opening:

This /usr/share/X11/xkb/symbols/psy file is my custom xkb keyboard layout, which does exist in that location. I have added its respective entry in /usr/share/X11/xkb/rules/evdev.xml, and it works flawlessly elsewhere (deb applications, Snaps, other flatpaks, login screen, recovery terminal, etc.).

When I remove this layout from GNOME settings (leaving the files themselves intact), I no longer get the error and ZapZap works just fine. I can even re-add the layout while ZapZap is open, and then use it inside ZapZap with no problems (though, of course, once I fully close ZapZap and try to re-open it, I get the same error again).

This issue does not occur on Wayland. ZapZap opens just fine with my layout when on Wayland.

Let me know if there's anything I can do to help.

Unfortunately I don't know how to help you with this problem as it is not directly related to the application.

Have you tried running the application from the source code?

Just tried running the application from the source code and this is what I get:

• I get the same issue when trying to open it with the instructions given in "Flatpak Development"
• Upon trying to run it with the instructions given in "Local Development", it runs perfectly fine
