[Erico <ericomtx@gmail.com>]

I have installed debian etch and would like to configure a laptop us keyboard

how can I do that ?

I've searched and found that this could be done in 

/etc/default/console-setup : 

XKBMODEL=""
XKBLAYOUT="es"
XKBVARIANT="nodeadkeys"
XKBOPTIONS="lv3:ralt_switch"

or  /etc/X11/xorg.conf :

Section        "InputDevice"
 Identifier      "Generic Keyboard"
 Driver          "kbd"
 Option          "CoreKeyboard"
 Option          "XkbRules"      "xorg"
 Option          "XkbModel"      ""
 Option          "XkbLayout"     "es"
 Option          "XkbVariant"    "nodeadkeys"

Now when I get into gnome it says my X11 configuration is diferent then gnome
