Using the vino, if use the vncviewer win32 version, the viewer window can be scaled without scroll bar.
however, under ubuntu the vncviewer can not, even with the command line option -geometry 1024x768.
Vncserver can set the default geometry, but vino can not (at least I don't find).
Thanks for the help and previous reply.
