Every time my machine is stumbling, I run a top command and the compiz process is eating a lot of CPU. How can I configure it to consume the minimum of machine resources? I don't care for fancy graphics or effects. I have an integrated intel graphic card.
My computer had an integrated Intel board. I've installed a new NVida 630 card and everything is great now. If I knew that it would improve so much, I'd had installed it before.
Long are the days where we could install Linux in old machines. If you have a weak graphic card, use Lubuntu, Xubuntu or Mint. After years re-compiling Gentoo, I just wanted the most used linux on the market. Bad choice for my machine.

To install Compizconfig settings manager open a terminal (ctrl + alt + T) and run this command (you can paste it into the terminal with ctrl + shift + v):
