Is the DISPLAY environment variable set and are you able to run other Xwindows applications from the command line? Perhaps try xdpyinfo.
It could also be an X11 access control problem. A quick search online for X11 "no protocol specified" showed a few people having problems running X11 applications as root (and I noticed you are running simh as root). The problem was due to a missing .Xauthority file for the root user. Check the environment variable XAUTHORITY.
