keyboard layout setting

[Amy4269]

I upgraded ubuntu from oneric to 12.04 LTS (Precise Pangolin). Im using severals layouts for my keyboard : English (US), English (US, International with dead keys), English (US, alternative international) and French.
I usually used English (US) but this morning my settings were changed and I have to precise each time I start my computer which keyboard to use. The default one is not conserved from one time to one other.
Cheers!
