Try with xterm, which generates much better error messages.  Possible
causes:  DISPLAY variable not exported, nothing listing on
mynotebook:0.0, "host +" or "xhost +otherserver" not run on mynotebook.

If you add the -X flag to ssh, ssh will automatically set $DISPLAY on
the other end and tunnel the display back to the local server.
