Comment 134 for bug 862430

Gregory, you can reinstall the ppa version of compiz (see mfwhite5's comment right after mine) then hold it using:

for i in compiz compiz-core compiz-gnome compiz-kde compiz-plugins compiz-plugins-default libdecoration0; do echo "$i hold"|dpkg --set-selections; done

The bash command above also stopped for me KDE's update notifier to pop up at every startup.
But remember, this will prevent every future update of compiz, when the next good version will appear you will have to install it manually.
