This is stupid.  I should be able to get the command-line options
BEFORE starting X:

    $ xtightvncviewer --help
    Error: Can't open display:
    $ xinit /usr/bin/xtightvncviewer --help
    [help output...]

Hi

This is probably so. VNC has a bit strange syntax.

Are you really sure you got VNC help screen here, and not xinit help?

man xtightvncviewer?

Hi Trent

Interesting. If you just type xtightvncviewer without the --help, then
you get the help text, right?

No.  Without arguments:

    $ xtightvncviewer
    Error: Can't open display:

If I run it in X (i.e. "xinit /usr/bin/xtightvncviewer"), it prompts
me for a server to connect to, by popping up an X client window.
