Perhaps I didn't speak english well and I don't know if I was understood for 
that. I wanted to say I saw 1/4 of the size of the s-c-d window;
Or you did a joke I didn't understood

I did what you said, but it seems I didn't get the expected results:

Video adapter: VESA VGA
Mode:    COLSxROWS:
0  0F00  80x25
1  0F01  80x50
2  0F02  80x43
3  0F03  80x28
4  0F05  80x30
5  0F06  80x34
6  0F07  80x60

So, no graphic mode as I could find by googling
http://tldp.org/HOWTO/Framebuffer-HOWTO-5.html

If I use, as an example, vga=0x307, when I startx, I can see saying 4 desktops 
on the width of the screen and height of these desktop are only 1/10 height 
on the screen, at the top of it
So, 9/10 of the screen is black.

Alain
