XScreenSaver(6x)                                              XScreenSaver(6x)

       queens - n queens screensaver

       queens  [-display  host:display.screen]  [-window]  [-root]  [-install]
       [-visual visual] [-delay microseconds] [-fps]

       The queens program solves the n-queens problem (where, in this program,
       N  is  between  5  and  10 queens) using a straightforward backtracking
       algorithm.  The problem is: how may one place N queens on an NxN chess-
       board such that no queen can attack a sister?

       queens accepts the following options:

       -window Draw on a newly-created window.  This is the default.

       -root   Draw on the root window.

               Install a private colormap for the window.

       -visual visual
               Specify  which  visual  to use.  Legal values are the name of a
               visual class, or the id number (decimal or hex) of  a  specific
               visual.   -fps  Display  a running tally of how many frames per
               second are being rendered.  In conjunction with -delay 0,  this
               can be a useful benchmark of your GL performance.

       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.

       It's not unknown for this and other OpenGL hacks to fail under hardware
       accelaration (UtahGLX) and take the X server with them.  Texture images
       must be 16x16 or 32x32 or 64x64 etc.
