The tool Xvfb can be found on other distributions like SuSE, too; there 
it is contained in an RPM called xextra*. When you have installed Xvfb, 
try starting it up via something like

/usr/X11R6/bin/Xvfb :0.0 -fp 
/usr/X11R6/lib/X11/fonts/100dpi,/usr/X11R6/lib/X11/fonts/misc -fn 

where you have modified the parameters and paths to your liking. Don't 
forget to set up DISPLAY accordingly depending where you want your X 
apps to connect to. According to several comments I have read, JDK 1.4 
can work headless, so does not require the virtual frame buffer under 
Linux anymore, but as far as I have tested it, Batik does not produce 
any visual result under JDK1.4. I am still checking out that one. When 
you are working more closely with Batik, check out the 
JPEGEncoderImpl-bug of Sun so you do not run into that one; I sent a 
test and patch to this list some days ago.
