I have bought a new DELL laptop( Inspiron 5050 ). I am able to control brightness in windows 7 through f4 and f5 keys. Now i have installed ubuntu 10.04. The problem is that the function keys f4 and f5 are not working here. I have also tried combination of fn and function keys( f4 and f5 ).

What should i do now? Do i need to install any extra package to control the brightness in ubuntu 10.04?

Do your other function keys work? Like the keys for volume control?

A few people seemed to have solved the problem by installing gnome-power-manager and uninstalling xfce-power-manager.

This thread may be of some help.
