Xorg crash when no display attached

[Taleman]

Binary package hint: xorg

Computer is Foxconn nT-330i. It has DVI and HDMI display connectors. If no monitor is attached, X crashes when Ubuntu boots.

I can get X to start properly by attaching a monitor do DVI connector and doing
  /etc/init.d/xdm stop
  /etc/init.d/xdm start

Tried to get a backtrace or crash dump of X, not sure if this is the same situation as above. I started
  gdb /usr/bin/Xorg 2>&1 | tee /tmp/gdb-Xorg.txt
