Problems with Xorg

Hi other time:

Finally, I could install the current image of Debian GNU/Hurd in VirtualBox.
I selected Xfce desktop in the installer, and this feels installed
correctly.

But, when I try to launch xorg using startx, xorg don't starts, and shows a
black screen. I wait many time, but It don't starts.

I have shared my VM via torrent. I attatched the torrent file to this mail.
If you can run the VM and check the error, I will be gratefull.

Thanks
