Keyboard not working in KDM

[Luca Bertoncello]

Hi list!

I'm installing my new PC, using Debian 8 and KDE.

Well, the basic are installed and it works, but I have a strange problem...
If I want to log in, I don't have any problem, but if I want to shutdown the
PC, I can't type the admin-password (so I configured KDM).
I use KDE 4.11.13 from Debian repositories and I can send the configuration
files you need.

Can someone help me solving this problem?

Thanks
