Repository: kde-workspace


Description
-------

In this patch, I
  1.  add a QElapsedTimer to prevent PowerDevilUPowerBackend::brightnessKeyPressed been called twice successively
  2.  let KDE override the BIOS's brightness change.  This makes the OSD show even if BIOS also handles the key press.  (It also because KDE allows more brightness level at my own laptop than my BIOS, but it may not be true for others.)
