Keyboard shortcuts are broken on FreeBSD
This is GNOME Shell 3.34.0-119-g3e58af10 and Mutter 3.34.0-14-g0e69fe078 on FreeBSD 12.0.
Keyboard shortcuts, such as Print Screen and Ctrl-Alt-Shift-R, no longer work after !618 (merged). Pressing these keys does nothing and shows a warning on the terminal:
(gnome-shell:7154): Gjs-WARNING **: 00:50:29.192: JS ERROR: Error: Argument 'string' (type utf8) may not be null

_emitAcceleratorActivated@resource:///org/gnome/shell/ui/shellDBus.js:154:39
GnomeShell</<@resource:///org/gnome/shell/ui/shellDBus.js:30:17It can be worked around by commenting out the line which adds device-node to params:
151 let connection = this._dbusImpl.get_connection();
152 let info = this._dbusImpl.get_info();
153 let params = { 'device-id': GLib.Variant.new('u', device.get_device_id()),
154 //'device-node': GLib.Variant.new('s', device.get_device_node()),
155 'timestamp': GLib.Variant.new('u', timestamp),
156 'action-mode': GLib.Variant.new('u', Main.actionMode) };I know mutter!678 (merged) attempted to fix it, but it is still broken because clutter_input_device_get_device_node just returns NULL. It seems the reason of returning NULL is that the keyboard device kbdmux doesn't have Device Node property. Keyboard and mouse use xf86-input-keyboard and xf86-input-mouse drivers, respectively.
