@mitu ok right it finally works. I found the CTRL and F1buttonns and configure the keymap

It works on everythink except on the number pad.. i think there is a problem with the NUM bouton. I see that the NUM led dont light when i push it.. i test on another key and its the same... my configuration configures the page up bouton and not the 8 bouton i think

The same problme appears with CAPS bouton, does raspberry support the changing of CAPS and NUM
it ligh on my computer but not in the raspberry
