I have a Gateway FX with an Nvidia 9800 Geforce card and I keep having this problem with the display going blank and the sound looping. It only happens when on AC power. The only way out is to hard reset the laptop. There is a way to fix this with a Windows OS and RivaTuner by forcing a constant 3D performance level. I was wondering if there was anyway to force the level in Ubuntu.
