Description of problem: The GLHanoi xscreensaver, which can be executed as a standalone program, does not recognise the 'speed' option. The man page for glhanoi says the '-speed number' option set the speed of disk animation. However, running /usr/libexec/xscreensaver/glhanoi -speed 15 shows the following output: ----------------------- GLHanoi: from the XScreenSaver 5.04-1 distribution (13-Nov-2007.) http://www.jwz.org/xscreensaver/ Unrecognised option: -speed Options include: -root, -window, -mono, -install, -noinstall, -visual <arg>, -window-id <arg>, -pair, -light, -no-light, -fog, -no-fog, -texture, -no-texture, -count <arg>, -delay <arg>, -wireframe, -no-wireframe, -fps, -no-fps. ----------------------- This is inconsistent with the man page. Perhaps the version of GLhanoi is an old which does not have the latest options built in?? Version-Release number of selected component (if applicable): xscreensaver.i386 1:5.04-1.fc8 How reproducible: Always Steps to Reproduce: 1. View man page for glhanoi. See 'speed' option. 2. Run glhanoi with 'speed' option. 3. Output says 'speed' option is unrecognised option. Actual results: Does not run with speed option. Expected results: Run glhanoi with varying speeds set by that option. Additional info:
Thank you for reporting this bug. Well, actually glhanoi has never supported -speed option and the error message is correct. As xscreensaver has more than 200 hacks there are sometimes mistakes in the description in man package :( I will ask Jamie to fix glhanoi man page from next version. By the way, if you want to change the speed of glhanoi, please try to use -delay option (I guess most hacks support -delay option since 5.00)
The -delay option controls the speed of the camera velocity as it flies around. What I was interested in is speeding up the speed of the colored disks as they move from one pole to another ie. number of colored disk movements per minute. This seems to be set by the -speed option as detailed in the man page. The actual implementation of this option would be useful, especially with larger numbers of colored disks. In addition, there are other options in glhanoi man page which are not actually available when glhanoi is run.
