When you say "connecting to it", do you mean a long-running instance
of the server (e.g., you typed "vncserver :18" last week; today you
said "vncviewer :18")?

When was the last time you connected successfully to this instance of
the server?

It sounds like a window-manager issue.  "ps xf" and look for
descendants of "Xvnc" -- any *wm processes?  twm, fvwm, mwm, icewm?
That would be the window manager.  

You are running /etc/X11/xinit/xinitrc?  You could replace this line:

exec /etc/X11/xinit/xinitrc

by this:

sh -x /etc/X11/xinit/xinitrc 
sleep 99999999

then kill your vncserver instance on :18 and restart it... then check
the log.

...

What is the mtime of the log file (e.g., what does "ls -l /log/file"
say)?
