Is there a trick to use the Fn<function keys> with non-Unity? I am not a fan of Unity so the first thing I did to my brand new (awesome!) pangolin was put xubuntu on. In Unity all the Fn<function keys> work but in Xubuntu only the wifi (F11), bluetooth (F12), brightness (F8,F9) and turn off mousepad (F1) work. The multimedia keys, sleep and suspend don't work. What is the trick to get them working under XFCE?
