Can I run NExS on a display-less machine on my network as a spreadsheet server for printing spreadsheet data or controlling access to a global data set?
Normally, NExS needs to run on a machine with an X Windows display. However, there is now an X server available which does not require a physical display. NExS can run on a display-less machine with the aid of this X server. The information on this X server is reprinted below: Subject 113: Is there a “pseudo-tty” or fake X display I can use? Applications often have a need to run against an X display which isn’t tied to a physical display – perhaps to make a screendump, or to run when the software expects to have an open display. In these cases, the X Virtual Frame Buffer can be used. It is a full X server which doesn’t open any devices (the output can be a memory-mapped file) but which otherwise behaves as an X display. It is also useful for testing. The Xvfb is part of the X11R6 distribution, in programs/Xserver; set the configuration option in config/{machine}.cf to build the distribution with this server.
