Hi,

I'm trying to have dis-similar modes on each head (1400x1050 on one,
1024x768 on the other) in clone mode...but it doesn't work.

I have my main screen (LVDS) in 1400x1050 and my second (VGA) in
1024x768. But on the VGA one, I don't have my complete desktop, just a
part of it (a rectangle, which its size is 1024x768 of the complete
image (1400x1050)).

Which changes must I do ? changes in xorg.conf ? or just through xrandr ?
Thx,
