How to : Make Compiz smooth and fast without tearing in ubuntu 10.04

Compiz does not seem to run as smoothly as Metacity on my desktop system. With
With desktop effects switched on, I’d also notice tearing in areas of the screen with fast motion including in videos. I was fiddling with Compiz settings recently and managed to fix the problem entirely.
If you haven’t already installed the compiz configuration settings manager, install it by running the command:
sudo apt-get install compizconfig-settings-manager
Start CCSM from System->Preferences->CompizConfig Settings Manager. Under the category General, select General Options. Select the Display Settings tab. De-select the Detect Refresh Rate option. Set the Refresh Rate option to match the vertical refresh rate of your display. (I checked my monitor’s on-screen display to verify that it was running 60 Hz.) Finally, select the Sync To VBlank option.
If you didn’t find compiz smooth enough turning the refresh rate up a bit wont hurt.

What does it do? :
ppa-purge will “reset all packages from a PPA to the standard versions released for your distribution in a single command”. So basically its like a way to “restore your system” back to the way it was before you installed packages from a PPA.
