Comment 8 for bug 179138

I've just updated to Kubunuty Jaunty 9.04 latest Beta

Most keys work, except Fn-F3 (Sleep) or Fn-F8 (Show Power)

Fn-F3 is catched in xev, but doesn't seem to be mapped to anything:
KeyPress event, serial 34, synthetic NO, window 0x4000001,
    root 0xc2, subw 0x0, time 6963639, (-35,769), root:(667,794),
    state 0x0, keycode 150 (keysym 0x1008ff2f, XF86Sleep), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

Same goes for the Battery button
KeyPress event, serial 34, synthetic NO, window 0x4000001,
    root 0xc2, subw 0x0, time 7054314, (-201,692), root:(501,717),
    state 0x0, keycode 244 (keysym 0x1008ff93, XF86Battery), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

Doesn't seem to be mapped to anything.
