Thanks IOhannes and Frank !

So, if i understand (as my french-english is quite bad), there's no solution to
get the gemwin on the external screen and the patch on the laptop screen, with
that type of card. I had managed to display "clone" and "extended" screen. But
under windows 2K (glups !) i can get an extended desktop and the video is
rendered (for example, with VLC player) on the external screen. Maybe this
because this is not OpenGL. In this case, couldn't it exist a trick to render
it as non-3D (wich doesn't interest me, i'm doing 2D with Gem, because i know
it better) or something like passing it from Gem to pdp ? If I remember well
the workshop i did, there's something like gem_to_pdp... Or should I use pdp in
case of Gem ?

About the Intel Graphics, I heard that Intel had just made their drivers more
open, dont't they ? Do you think, there will be more support for these cards
later with linux ?

However, now, I'll try with my girlfriend laptop ; i hope her graphic card is
different !

Thanks once more
