Those effects come with Compiz. Its installed by default in all distributions Gutsy Gibbon ( 7.04 ) onwards. You can enable it by right clicking the desktop, choosing Change Desktop Background > Visual Effects. You will probably see 3 options here - None, Normal and Extra. To get the effects, you may choose either Normal or Extra but that doesn't give you the 3D cubes. For that you need to install another package - compizconfig-settings-manager. Just do a "sudo apt-get install compizconfig-settings-manager" in the terminal and you will have it. Then go to System > Prefereces > CompizConfig Settings Manager. There you can configure the 3D effects. The "Desktop Cube" option needs to be enabled to get what you want. Play around with it.

But almost 2 years ago, I saw my friend show me some magic 3d and transparent desktop on linux system. We can switch desktop like a cubic and it is more fascinated than visa. I have no idea whether the window manager is kde or gnome. If I want to have the same thing happen on my ubuntu, what package I should apt-get? Does my HWs need to upgrate? appreciate your help, miloody -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>
