Experimente o Displex . Ele fornece as mesmas opções do Fusion Icon e funciona com Unity / AppIndicators.
( Ele também funcionará na maioria dos outros ambientes de desktop onde você pode executar o compiz ).
Note que, se não for executado, tente o seguinte:
I installed the deb and tried starting DisPlex from the app menu but nothing
happened. So I ran "indicator-displex" from terminal. At some point it showed
"Value error: gconf key /apps/nautilus/preferences/show_desktop has no value"
so I had to manually add a value and typed
gconftool-2 --set "/apps/nautilus/preferences/show_desktop" --type bool true
ran it again and got the same error for
/apps/gnome-screensaver/idle_activation_enabled,
so the same procedure and that was it.
