You can't run an X server on s390 because s390 has no graphical console to display things on, as you noted above. It is possible to run graphics applications on s390 (i.e. an X client) but they must be connected over the network to a remote server (i.e. a PC running the X server). I know this is possible. But I don't recommend it. As much as I like the mainframe, it really wasn't designed for this type of application. The mainframe is much better suited for back-end servers, such as SQL databases, web servers, ftp servers, etc. Just think about it. All the user interface devices (keyboard, mouse, graphical display) are on a remote PC and all those screen updates and mouse mickeys (yes, that is what they are called) have to go across a high-bandwidth network connection to keep decent response time. It chews up a lot of network bandwidth and (very expensive) mainframe CPU cycles. It's possible to do, but in my humble opinion it just isn't the right platform for this type of application. You're better off doing something like a browser-based application, with the browser running on somebody's PC and the web server and its server-side programming running in a virtual machine under z/VM. -- .''`.
