what graphics hardware do you have (use lspci to find out)?
This sounds like you're perhaps using a higher resolution/colour depth than your video memory can support.
Does the same thing happen if you use Xorg-7.7 instead of Xvesa?
Hi Juanito,
i tried lspci but it's different form what i'm used to see :
