Using KDE,   Fn+cursorPad UpArrow or Fn+DownArrow (bottom right of 
keyboard) doesn't change the brightness of the display.  Fn+UP/DOWN does 
change the display brightness in Fedora 8  (surprise!) and in Vista (no 
surprise).

When the brightness combination is pressed with  lshal -m  running,  I show

Start monitoring devicelist:

xev  shows (in part)

    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

Any ideas?

Thank you,
