I have just removed Kubuntu from my eeepc and replaced it with Sidux. Everything works as it should - except for the keyboard shortcut keys eg Fn + F8 = volume down. I have installed all of the eeepc bits and pieces from sid BUT it still won't work. I feel that I am missing something really obvious.
Lesson learned : don't mess!!! Kubuntu was running fine
Curiosity killed this cat.
