Once again, I have to emphasize that I am *not* an expert, nor have I ever used Xvnc, so I'm just going by what I have ready over the years; unfortunately, I can't tell U off-hand where I happened to read these things, other than to say that it was most likely on the RealVNC website.

I poked around on the RealVNC website a bit, and on the page


it says that there is an X server built into the vncserver. It also shows one case in which U want to have more than one X server (running one or more copies of "vncserver"). In fact, much to my surprise, it also shows that U can attach "vncserver" to an already-existing X server. I didn't know U could do that!

Yes, that is another option but I think it is slower.

"vncserver" is an X server, with its own "display;" U work with it by setting the DISPLAY environment variable to the appropriate value (:1, :2.0, :0.1, etc.), just like U do with X11.

Right. I have been using it on Linux/UNIX systems for 15 years now. The thing I don't think I can do is run vncviewer on a Linux box that doesn't have the window manager running. Right? So I have to have a minimum of two X sessions going -- one in :1, say, and the other on :0, to be able to do what I want.

Connecting remotely isn't an issue. It's when I'm at the desktop on touching the machine that has my vncserver :1 running in it. To see it I have to run vncviewer, and to do that I need a window manager.

Maybe I could run Gnome in vncserver :1, and then use a lightweight window manager like ICEwm on :0. I do more work remotely than at the desktop. I do have a lot of memory and disk, though. The thing is I can't run two Gnome sessions at the same time.

Now Ubuntu is using Unity and I don't know how that's going to work out.
