Screensaver for Ubuntu Karmic

Ubuntu Karmic by default has very few screensaver modules enabled.
If you're a fan of screensaver, then I recommend you the following extra packages with install you more the 300 new modules.

Install instructions

sudo aptitude -y install xscreensaver-data-extra xscreensaver-gl-extra rss-glx

By the way, the rss-glx package gives you the beautiful skyrocket screen saver.
