xscreensaver-data 5.05-1ubuntu2 (amd64 binary) in ubuntu intrepid

 This package contains the so called "hacks" (the single screensavers
 that get displayed from a screensaver app). It is split out to be used
 with programs like gnome-screensaver that bring no own hacks, but can
 display them. Additionally it contains the various tools to load text
 or images from external sources.
 .
 This is the selected set of non-GL screensavers shipped by default:
 deco, distort, fiberlamp, fuzzyflakes, galaxy, metaballs, penrose,
 ripples, shadebobs, slidescreen, sonar, swirl.
 More hacks can be found in the xscreensaver-data-extra package.
