If so, this might help with the slowness that Bob noted, above. Would this method honor the

Perhaps it'll make for a tutorial sometime, but sticking with the "default" tools, vnc over ssh is a good option. @Hans – only problem is FreeNX isn’t packaged by Ubuntu so it would require some more work and the current clients either don’t work or are not free software.

It uses SSH already, it has many advantages over VNC, and it's a whole lot faster over any connection, especially slow ones. Forget VNC. Use NX.

Been around for many years. Write an analysis if encryption is necessary in most cases. Now that would be worth reading. Why does everyone write an article about VNC over ssh?

Now show us how to have a login VNC session that goes back to a login screen after closing, so one can login or different user can login. That's what is needed. Something that works like Windows Remote Desktop. Remote Desktop is already encrypted, by the way.

I just posted a question in the forums like 2 days ago and no one has responded to it? Please, if you have any info, post it in the forum.

Do you know if this is available from other standard GUI clients? For example, Remote Desktop Connections on Ubuntu, or Windows clients like UltraVNC? Also, can you restrict your VNC server to *only* accept secure connections? This is a good idea. Do you know if this is available from other standard GUI clients?

Always seemed weak to me that all you needed to take control of someone's whole screen if you had vino running was their password which can't be more than 8 digits anyways.
