The stable release of Ubuntu 11.10 Oneric Ocelot is now available for download. However, while using this release, I have noticed that the screensaver is not enabled when the computer remains idle for a specific period of time, what is shown is only a blank screen.
If you want to display a screensaver when your system is idle under Ubuntu 11.10, you need to install the xscreensaver package. Installing this package requires the uninstallation of the gnome-screensaver package.
Warning: Use this tip at your own risk!
Open the terminal and remove the gnome-screensaver package with this command:
sudo apt-get remove gnome-screensaver
To install the xscreensaver package and its plug-ins, run this command:
sudo apt-get install xscreensaver xscreensaver-gl-extra xscreensaver-data-extra

3. Enter now these details, then click Add:
Command: xscreensaver -nosplash
One last step consist now of customizing your screensaver. So, open xscreensaver using the Unity dash:
Then customize the screensaver the way you like:
