I have live Ubuntu (tried also Mint and Kubuntu, same effect) on a USB stick with persistence enabled. My laptop is however very noisy (VGA still on max?). I solved this problem before back with Mint 7 Gloria like:

sudo nvidia-xconfig

Ctrl+Alt+Backspace (restart xserver). VGA then behaved reasonably.

I can not reproduce these steps anymore with latest Ubuntu/Kubuntu/Mint.

Can the problem be that I'm on a LiveUSB? Is it normal, then when selecting "Additional Drivers" for nVidia they always fail to install (those proprietary)?

Yes, you can not install system packages from live usb installation. –  João Pinto Jan 20 '11 at 21:31
    
I tried f.e. NetBeans and they were installed successfully (persistence). So this is a difference? –  Xorty Jan 20 '11 at 21:33
