On my system, it seems that /etc/X11/xinit/xinitrc calls /etc/X11/Xsession and there is no ~/.xinitrc file. Suppose I make it so that /etc/X11/xinit/xinitrc doesn't start X11. I guess I would then see a console window after booting. Can I just run vncserver :1, say, from there, then run vncviewer from that console? It just seems like that would fail because I don't have a graphical interface. How can vncviewer run without a DISPLAY? By the way, I have been running Xvnc on :1 for years without any failures (that's RealVNC Free). It ran once for something like 500 days on Solaris. It's really the same on Ubuntu -- no failures -- but I happen to have the machine in a place where the power sometimes goes out and that has limited me to only about 200 days of uninterrupted uptime. Mike Mike: 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 http://kb.realvnc.com/questions/10/How+do+I+run+multiple+screens%7B47%7D sessions+of+VNC%3F 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! "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. It will work with your default window manager, or U can use a different one (changed in ~/.vnc/.something-or-other). If U modify xinitrc, U would change it to launch "vncserver" instead of "X;" as a general rule, I try Really Hard not to change system-wide stuff, but in this case, I'm not sure how to implement Xvnc in user-mode. If my understanding is correct, your X server would then be running on display :0.0. Since this would be a system-wide change, all users on the system would experience this change. So long as they interact with the X server using their window manager (which everybody does), they probably wouldn't notice any change (any differences would probably mean that one X server or the other had a bug, or was making an alternate assumption about something). Running "vncserver" as your primary X server would have the advantage of allowing anybody who connected your machine to see your desktop, just like it works on MSWindows; of course, working like MS Windows is not always seen as an advantage!
