Thanks for the information pandanuma, it was indeed the rss-glx (
Really Slick Screensavers) package that I lacked.
I downloaded the rss-glx package off of slackbuilds.org website from here:
http://slackbuilds.org/repository/13.1/desktop/rss-glx/
It built no problem. After installing the SB package following SB instructions, I ran the rss-glx-install.pl script in the utils/ folder in the installation directory. This updates your .xscreensaver file to include the new ss.
Unfortunately, the lorenz screensaver is a new one
, and not my old pal i remember. The Lorenz SS i remember was a fixed-camera plot of the lorenz attractor. The new lorenz ss in rss-glx is much fancier and swoops along the attractor in a 1st person mode. Cool, but not the exact thing i was looking for. I will still post this as solved though, and maybe update it later if I ever find the
ORIGINAL lorenz ss i remember from my first experience with linux on a Kubuntu 6.0 install.
