Installing Compiz on Debian Wheezy using Squeeze repo

NOTE1፡ It won't be possible to configure Compiz with "Compiz Config Setting Manager" because it requires python < 2.7(In Wheezy python is 2.7)
NOTE2፡ Some metacity related packages will be lock - not upgradable(main problem compiz from squeezy expects "libmetacity-private0" but in wheezy this package has small difference - "libmetacity-private0a")

1. Add squeezy repo to source_list(you can comment it out after installation):

sudo echo "deb http://ftp.ee.debian.org/debian/ squeeze main" >> /etc/apt/sources.list

2. Install compiz:

sudo apt-get install -t oldstable compiz compiz-gnome compiz-gtk libmetacity-private0 compizconfig-backend-gconf 

Now compiz should work the only thing is left - setup compiz:
Use gconf-editor:

sudo apt-get install gconf-editor

gconf-editor

OR edit directly compiz config file:

vim ~/.config/compiz/compizconfig/Default.ini

Example:

cat ~/.config/compiz/compizconfig/Default.ini
[core]
as_active_plugins = core;move;resize;place;decoration;minimize;shift;scale;

If compiz is laggy try:
