it may perform better if run as root (use the -root option.)
WARNING: Take care in using Xdummy, although it never has it is
possible that it could damage hardware. One can use the -prconf

The option -geometry can be used instead of -geom;
x11vnc calls Xdummy and Xvfb this way.
-nomodelines When you specify -geom/-geometry, $program will
create Modelines for each geometry and put them
in the Monitor section. If you do not want this
