On the remote end, you have to run "vncserver" or "xvnc" as the user you
intend to log in as remotely.  You probably ran vncserver on the remote
end as root, so you have to be root at the local end, too.  The "can't
read password" error is caused by the vnc server running as root and you
trying to log in as a mortal user.  The mortal user you tried to log in
as probably doesn't have a ~/.vnc/passwd file.

You mean the local VNC window is smaller than the screen size of the 
remote end, hence you have scroll bars.  You can either turn on
fullscreen (which really only works if your local screen size is the
same or larger than the remote end) or you can use the "-geometry"
option to specify your local window size.  If you use a 1280x1024
display locally, fullscreen mode is essentially:

	-geometry 1280x1024x0x0

No problem.
