Hi all,
I'm using kubuntu 11.04 and there is a thing that I don't know hot to resolv.
In kubuntu 10.10 the graphic bar o brightness worked well; if I pressed Fn + +/-, the brightness increased/decreased with the bar. Now, with kubuntu 11.04 (and other distribution with the new KDE, I think), the brightness increased/decreased but not the bar that even doesn't appear.
Any suggestion?

Thank you very much to all
