Tom; Your actually talking about three different things, really, and a bit of over lap too. This is high level, and not very detailed:
1.) X Windows (X11) is a grapchical display environment. 2.) VNC is not X windows. It pumps out a display env to a TCP Port. 3.) cygwin is a UNIX like operating env for Windows. Part of the UNIX like env of cygwin, you can install a free version of X windows too. To run VNC server on the S390, you would likely want X Windows running as well. Personally, a GUI is not why one typically puts Linux on a mainframe. I prefer to run X windows on some other server, and let the big iron do its prescribed job and not bother it with graphical work. It sounds like you already have people using X windows for other efforts. If that is the case are they using it from Windows? or UNIX? The licensing of X Windows for MS Windows can be costly. The two leaders in that market are Hummingbird, and Reflections X. Does this help? Let me know if I you need any more info.

Some of our Linux users want to use the X11 interface to access Linux/390 (Suse 8 under z/VM). Some of them have software already installed on their Windows PCs and use it for other platforms. Others just need software installed. And I have to have a X11 server installed. Now that I'm on Suse 8, and the install method kind of force the issue, I have VNCSERVER installed. On the PC, I have vncviewer installed. It seems to me that I have a X11 interface running. But I'm told by some folks here, that that isn't X11, vnc isn't compatable with X11 and there is different software for X11. I've been told that I need a product such as "cygwin". I've gone to the website and when I try to download it, boy is there a lot of stuff that would be downloaded. (perhaps I got the options wrong...I just took whatever defaults there was) This makes me believe that cygwin and vncviewer are quite different animals. Any comments?
