You were right all the way, it works now.
Thanks, I'm ready to verify my ARM platform

compiled a SDL program.
On ARM system, SDL doesn't receive good event ID (if I may call it like
this). When pressing any digit from wired keyboard, it works fine.
When pressing any digit from wireless keyboard, it receive : "numlock
key was pressed".
So Pygames is out of the loop, like you all suspected (I have to learn).
Now what do I do to progress in my investigation ?
Can I recompile SDL with different options ?
Is SDL relies on an other librairy ?
Both system have libsdl version 1.2
