In order for me to watch HD videos without tearing, I need to disable my Composite setting in xorg.conf

Section "Extensions"
    Option "Composite" "Disable"

But I love my transparency, so, how do I enable and disable it without restarting X? (Preferably using command line)

Use fusion-icon.

Or use "metacity--replace" for turning off composite effects (and "compiz --replace" for turning them on) ;) –  user2648 Nov 23 '10 at 15:37

You can't disable an X extension while the server is running - the X protocol simply has no way to tell clients “Oh wait, that extension that I said you could use is no longer valid and you'll crash if you try to use it now.” All you can do is stop running whatever composite manager you're using (as suggested in @iamsid's answer).

Found a better way to do it, just:

  1. Menu
  2. Settings
  3. Window Manager Tweaks
  4. Compositor Tab
  5. Uncheck "Enable display compositing"

I think this is better since it doesn't involve installing new application and it did help me prevent tearing when watching HD movies.
