Well, xscreensaver has the option "ignoreUninstalledPrograms" option (in ~/.xscreensaver and some system-default xscreensaver config file: on Fedora it is /usr/share/X11/app-defaults/XScreenSaver which is the symlink to /etc/xscreensaver/XScreenSaver.ad. The settings on ~/.xscreensaver are given higher priority).
If you set "ignoreUninstalledPrograms" to "True", on xscreensaver-demo hacks not installed are not shown (which may be against your desire) and "up/down" arrow tries to launch installed hacks only. Note that "ignoreUninstalledPrograms" cannot be changed with xscreensaver-demo GUI. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
