I've had similar issues with the ttylinux image and found VNC usefull
for debugging. Add the following to ttylinux.one

 GRAPHICS = [
   type    = "vnc",
   listen  = "127.0.0.1",
   port    = "5904"
 ]

This gives you a VNC console on "screen 4".

Also see my other email to this list, the ttylinux image root fs needs a
check.
