Lifesaver it’s a screensaver for GNOME that displays recent posts about Ubuntu from Twitter and Identi.ca.

For the last couple of ubuntu versions, gnome-screensaver, which is also the gnome screen-locking program, has been using gtkbuilder .ui files for configuration; unfortunately almost all of the third-party themes (e.g. on gnome-look.org) use .glade files. Here's how to convert a .glade file to a .ui file for use with current versions of gnome-screensaver:

Most of us go away from our computers. When we do we don’t much care to come back to see our screen just the way we left it. We have been trained that a screensaver should take the place of our work or our play on our monitors. I have been asked numerous times “How do I have screensaver X on my Linux desktop?”

The Eternity Screensaver plays animations of ray-traced scenes which took days or even weeks to generate. The reasoning is that these clips should look more impressive than anything which can be generated on-the-fly.

This Ubuntu application adds actions to the corners of the screen in GNOME, such as switching virtual desktops and controlling the volume. You can even enable the screensaver and control the screen brightness on your laptop.

Malware has been found hidden inside an innocuous 'waterfall' screensaver .deb file made available on popular artwork sharing site Gnome-Look.org.

I recently got the Compiz Screensaver running on my Ubuntu Linux system. This is a somewhat experimental plugin and so this plugin is not included by default with Compiz.

I'm going to show you how to run a screensaver as the desktop wallpaper in the gnome desktop environment. You need to be using gnome and have the xscreensaver-data package installed in order to accomplish this task.

Okay, I lied right from the start with that title. Don’t get into thinking that you can get any real security out of this, as it is equivalent to a locking screensaver. In fact, this is just a screensaver add-on for GNOME. That said, it does prevent the occasional hyperactive child or devious coworker from messing with your desktop when you are away and forget to lock it.
