compiz-switch howto
sudo apt-get install fusion-icon

You can run Fusion-icon immediately by opening the Run Applications dialog with Alt-F2 and typing fusion-icon. Note that this will cause Compiz to restart.

To start Fusion-icon whenever you log in, add it to the Startup Programs list in System->Preferences->Sessions.

I haven’t found a package for Ubuntu 7.10, but those who are waiting until the final 8.04 release to upgrade can also use the similar Compiz-Switch application instead.

[update] emiligene has posted a Ubuntu 7.10 repository for Fusion-icon in the comments:
deb http://ppa.launchpad.net/maco.m/ubuntu gutsy main restricted universe multiverse
Thanks!

[update] An anonymous commenter has pointed out that running fusion-icon -n will prevent the application from unnecessarily restarting Compiz when it starts. You should use this command instead.
