Hi all,

you have to put something like this in youre xorg.conf:

Section "InputClass"
    Identifier "keyboard"
    Driver "evdev"
    MatchIsKeyboard "on"
    Option "xkblayout" "de"
    Option "xkbvariant" "nodeadkeys"
EndSection

Section "InputClass"
    Identifier     "Logitech MX Revolution"
    MatchIsPointer "on"
    Driver "evdev"
EndSection

Note the "InputClass" instead "InputDevice"
