RedHat 9 (Linux i386) - man page for queens (redhat section 1)

       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 chessboard 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
