  #To add your own modes here, use a modeline calculator, like:
  # cvt:
  # http://www.x.org/archive/X11R7.5/doc/man/man1/cvt.1.html
  # xtiming:
  # http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
  # gtf:
  # http://gtf.sourceforge.net/

  #This can be used to get a specific DPI, but only for the default resolution:
  #DisplaySize 508 317
  #NOTE: the highest modes will not work without increasing the VideoRam
  # for the dummy video card.
