[Bug 318327] Re: cannot control backlight on lenovo t400 with KDE 4

[lucky]

Thanks for replying, 
It seems  to be a configuration problem, what I actually don't understand, is why when I choose a gnome session with GDM I get the back-light controls, whereas I don't when I choose a KDE session.
I am normally using the Intel graphic adapter.

As I said in my first, I still can use acpitool -l to change the
backlight within command line.

And I experience the same problem from an Intrepid ubuntu (gnome) with
Kde 4.2 packages installed from the ppa and from a fresh install of
Kubuntu jaunty on a fresh partition.

I will run dmesg once again and see what's going wrong.
Is there a way to know whether a key stroke triggers the event  associated with or not?
