Try running the DM first, then running Xdomain.  The blank screen means
you have successfully switched but there is no DM to switch to.  I run
Xdomain from a pad and have no problems with switching.  When Xdomain is
told to switch, all it does is release control of the display and input
- its up to another process (the DM) to notice and start using them.
Here are a couple of handy shell scripts for switching:

     # xd : switch from X to DM
     # Send a SIG USR1 to Xdomain
     /com/sigp xdomain -c 09010010


     # dx : switch from DM to X
     # Send a SIG USR2 to Xdomain
     /com/sigp xdomain -c 09010011
