Comment 111 for bug 876198

The "Lee (lee-sodnpoo) wrote on 2012-02-18" solution works for me. However I will add a couple advices.

First deinstall compiz "sudo apt-get remove compiz*" and "sudo apt-get autoremove" all without cuotes.

Proceed like Lee says and after that, declick the Natty repositories from the Update Manager.

Besides, add the following packages to the "ignored packages" (I'm translating form spanish so not sure this is the righ tab name) in the Update Manager to be sure compiz will not update:

compizconfig-backend-gconf, compizconfig-settings-manager, compiz-core, compiz-gnome, compiz-plugins, compiz-plugins-extra, compiz-plugins-main, libcompizconfig0, libdecoration0, python-compizconfig.
