is there a widget (or maybe a feature/module embedded to KDE that i need to activate) for showing the screen brightness of my laptop? i am just asking for a simple bar that shows the brightness.
(os: debian wheezy & kde 4.8.4)

A screen brightness controller is available if you click on the battery applet. Otherwise, if routed through Powerdevil, a popup (similar to the volume one used by KMix) should be shown when the screen brightness is changed.

I am having difficult regarding this screen brightness bar.

Just last month i installed fresh copu of Kubununt 14.04. The brightness increase and decrease was working fine with default hotkeys on my lenovo Z500.
Just couple of days ago, the brightness doesn't change as per before (in same steps) and bar doesn't appear as it does with volume change.

Please help.


Thanks.

click on the battery applet, it there Screen brightness setting

not necessary embedded any module, there is setting on default laptop setting.
