-* X11: not available now, but on top of my ToDo-List!
+* X11
+  thanks to Herbert Rosmanith <herp@wildsau.idv.uni-linz.ac.at> a driver for the 
+  X Window System is available. It supports any size at any resolution. A very
+  small XLCD4Linux-Window can even swallow on the KDE Panel!
+  
+* Raster formats:
+  a generic raster driver (which is used by the X11-driver, too) is availiable,
+  PPM (portable pixmap) is the only output format at the moment. I'm working
+  on PNG!
 
 * other displays: lcd4linux and especially the display driver code is very modular, 
   so it should be quite easy to write a driver for any display. See README.driver
