Try logging in as admin and try changing your keyboard layout
to another one. I really do not know as I only use U.S.
if you cannot get it to work that way do a search for azerty keyboard layouts on the web.
I use the Dvorak keyboard myself, and so I was rather distraught that I had to go into QWERTY for my login screen. But I eventually figured out that if you log in as root at the login screen (using the same password as the first administrator account you created when you installed OSX), go into the keyboard control panel, and change your settings there, that the root settings apply to the login screen. Though I'm using Dvorak and not an AZERTY board, I see no reason why it shouldn't work for you.
soory but i may have not well understand.
First, i'm always in as root.
Then I went in the international part then to keyboard menu.And the only keyboard selected is the english one.
What is wrong?
