The first thing to check when you get the above error is the contents of the
DISPLAY environment variable. If SSH's forwarding magic is in place, it
should be localhost:10.0 or similar. (The number varies but the hostname is
always localhost.) The trouble could be as simple as some shell
initialization overriding DISPLAY.
