dvi output on powerbook g4 15" (5,6)

Hi list,

I'm trying to use the dvi output (without vga adaptor) on my mac. It
works well if (on the same screen) I use the vga adaptor, but when I use
a dvi cable (working on osx), it suddenly doesn't work anymore. Well,
Xorg detects it, and adjust the pseudo xinerama mode, but nothing is
displayed on it (as if the macintosh detected the screen but the screen
didn't detect the mac).

Is anyone had made working the dvi output without vga adaptor ?

Regards,
