There are a few things that I noted, though: I can’t say how useful it is for real world problems because I’m just playing with it on my kindergarten projects, but I enjoyed working with it so far. You can set X display when running Xvfb Xvfb :display_nr & and then use it as in previous option.Wolfram Mathematica provides a comfortable machine learning framework to play around with. It is pretty simple and straightforward to use. Install locally Xvfb which is a X server frame-buffer. Basically it boils down to setting the environmental variable export DISPLAY=machine_address:0.0 or passing during each execution option -display machine_address:0.0. To have an working front end on Linux machine without X server and windows manager installed you have the following options: This will invoke the front end from the terminal, allowing you to export the graphics. What you can do, if you have a working front end, is to use: Without a Front End you do not have graphics to export. The rendering of graphics are entirely covered by the frontend. You need a front end to export graphics from the MathKernel. The problem with the other machine, as the answers to this question make clear, is that there was no X server and so the front end could not be invoked. Rather, on the machine with version 6, the front end was being invoked silently. It turns out there is no difference between version 6 and version 7 in this regard. Presumably because X11 is not installed on the machine. PS: Version 7 introduced the function UsingFrontEnd but that fails with Developer`UseFrontEnd::nofestart: So the question is, how can I get the Mathematica kernel, sans front end, to export images? Why does it work without a hitch in Mathematica 6.0? If the above example works for you in version 7, please let me know! With similar errors for any other image format I can think of. That works fine on a machine with $Version = 6.0 for Linux x86 (32-bit) (June 2, 2008) but fails on a machine with $Version = 7.0 for Linux x86 (64-bit) (November 11, 2008) with the following error: Export::nofe: A front end is not available export of PNG

Consider the following dialog with the command-line interface to the kernel: $ math
