sudo apt-add-repository ppa:vanvugt/compiz-preproposed sudo apt-get update sudo apt-get install compiz=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- core=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- gnome=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- plugins=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- plugins=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz-plugins- default=1:0.9.7.8-0ubuntu1vvpreproposed2 libdecoration0=1:0.9.7.8-0ubuntu1vvpreproposed2 (it will downgrade packages, allow it to continue) Start synaptic in "Search filter": put "compiz" select every package that has a (!) next to it.
