Weird, Onboard showing a different layout than it types isn't supposed to happen anymore.
When you switch between typing on a physical keyboard and Onboard, do you see Onboard's key labels changing to a different layout?

Please run these in a terminal and attach the ouput:
setxkbmap -query
setxkbmap -print
xmodmap -pke

Then try this and see if it coaxes Onboard into typing bépo:
setxkbmap fr bepo
