Comment:
appmenu doesn't work without below steps in xfce:

add in /etc/environment:

export GTK_MODULES=appmenu-gtk-module

install:

appmenu-gtk-module appmenu-gtk3-module
appmenu-register

and resolve a bug in schemes:
create org.appmenu.gtk-module.gschema.xml in

/usr/share/glib-2.0/schemas/

contents:

```javascript
<?xml version="1.0" encoding="UTF-8"?>
<schemalist>
  <schema id="org.appmenu.gtk-module" path="/org/appmenu/gtk-module/">
