Comment 123 for bug 207473

Afunix: I found a work-around to this problem.
Open up "Global Keyboard Shortcuts" in system settings and select "KDE Daemon" in the
KDE Component drop-down.
There you should see the Decrease/Increase screen brightness, I just set both to
custom: none and after that I only got one brightness-change for each keypress,
however I still get two events in `lshal -m` and in xev.
I can live without a progress bar telling me how bright my screen is, after all I'm looking at it.
