Cannot enable Compiz

[dbzkid]

On my system compiz was working fine; until I did an update, It updated a few things like vlc and pidgin, but after I rebooted Compiz didn't want to start. I am not totally sure why.
My Graphics card is a Nvidia GTX 470; and I have installed the latest driver from Nvidia. This is what I get when I try to run compiz from terminal.

kevin@kevin-desktop:~$ compiz
compiz (core) - Fatal: No valid GL extensions string found.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

and my Xorg.conf looks like this:

Also It is running through an Hdmi cable (although I don't think this really matters).

I had the same issue, easily resolved.

First, let me ask:

If your car all of a sudden stopped moving because the engine quit, what is the first thing you look at? The gas gauge.

So, if you have video issues, what should be the first thing you look at? The driver.

Reinstall it.

Well thank you! It worked.
