Re: Can not run an installer file ..help
STOP.
Before doing a manual install of an Nvidia driver, go to Ubuntu Software Center and use the Edit menu to open the Software Sources program.
From there, you can easily install Nvidia drivers. (That's for 12.10 - if you're using 12.04 you need the Additional Drivers program, available from the Dash or from System Settings). It's much easier than doing it manually, and there are other benefits too, namely that you don't have to keep reinstalling the driver each time you install a kernel update. The version Ubuntu can help you install is the safer option, basically.
ONLY if you know you need the version from the Nvidia website, which is sometimes newer and sometimes supports newer hardware, should you attempt a manual installation of the driver from the Nvidia website.
Your problem is that you're still running the graphical display. The Nvidia driver from the Nvidia website doesn't like to be installed with your graphical desktop still active. You need to temporarily turn it off:
Code:
sudo service lightdm stop
You'll be dropped back to a text-only terminal where you can do the Nvidia driver installation. When done, type:
You need to do this every time you install a kernel update. Every. Single. Time.
Please, unless you have no other option, just use the version that Ubuntu helps you install, as you can simply install it once and it will work forever.

I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
