X11DRV_KEYBOARD_DetectLayout - layout not found

[Matthias Meyer]

Hello,

I try wine on my Thinkpad 600E with knoppix, a debian based distribution.
At start of any windows-program I get a message:
fixme: keyboard:X11DRV_KEYBOARD_DetectLayout Your keyboard layout was not
found!
Using closest match instead (German keyboard layout without dead keys) for
scancode mapping.

Where I can define the keyboard layout?
How to define a german notebook keyboard?
