Linux: keyboard switching no longer working since Ubuntu 24.04 #1505

The keyboard switching code in the GnomeShellIbusKeyboardSwitchingAdaptor uses the org.gnome.Shell.Eval dbus method to switch keyboards. This is deprecated since Gnome 41 and no longer works.

The best solution might be to create or install a shell extension and adjust the code to call the method names. See https://askubuntu.com/a/1501535.
