The best way I've found is to establish an X virtual
frame buffer (Xvfb) as a display. I run an Xvfb
that will dump to device :99

I then simply set the display device

>setenv DISPLAY :99

If you have saved off a bundle, then you can use a little isl to
automatically generate an image.

<?xml version="1.0" encoding="ISO-8859-1"?>
<isl debug="true" loop="1" offscreen="false" sleep="3600">

  <property name="basedir" value="/data/"/>
  <property name="imagetype" value="png"/>

  <!-- make an image -->
  <bundle file="${islpath}/MyBundle.xidv"/>
  <image file="${basedir}/Image_${yy}${MM}${dd}${HH}${mm}.${imagetype}"/>
