queens(6) XScreenSaver manual queens(6) NAME queens - n queens screensaver SYNOPSIS queens [--display host:display.screen] [--window] [--root] [--window-id number] [--install] [--visual visual] [--delay microseconds] [--wire- frame] [--fps] DESCRIPTION The queens program solves the n-queens problem (where, in this program, N is between 5 and 10 queens) using a straightforward backtracking al- gorithm. The problem is: how may one place N queens on an NxN chess- board such that no queen can attack a sister? OPTIONS queens accepts the following options: --window Draw on a newly-created window. This is the default. --root Draw on the root window. --window-id number Draw on the specified window. --install 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. --wireframe Render in wireframe instead of solid. --fps Display the cur- rent frame rate, CPU load, and polygon count. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. BUGS 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. SEE ALSO X(1), xscreensaver(1) xscreensaver-settings(1), xscreensaver-getim- age(6) COPYRIGHT Copyright (C) 2002 by Blair Tennessy.
