the nvidia-glx package (which you'll find after asking your package management system for nvidia or geforce drivers) suggests nvidia-settings here. the default is to install suggests. and that creates a nice menu entry in the system -> configuration menu. Yes, it'd be easier if nvidia supported randr, but the distributors did a very nice job of making it pretty easy.

Weird. Every time I stick a piece of hardware in a Windows box it doesn't work. Then I install the drivers from the CD and it still doesn't work. Next I get the drivers from the vendors site and then it sometimes works. In the final step I figure out the chipset and get a driver from its creator and then it works most of the time.

With Linux all I do is check about the state of the hardware support before buying and most of the time it just works without doing any of the above.

That's probably the worst brushless dc controller ever built. As you can see in the video the circuit cannot recover from too low rpm of the motor. He mentions better waveforms at the bottom of the site, though.
A proper sensorless BLDC controller measures the back EMF at the undriven coils and uses that information to figure out which coils to drive. Also you don't need a common ground for the coils, instead the polarity should switch when both ends of a single coil have the same potential. Of course it's possible that each of the coils actually has a third contact in the middle.
Properly driving a sensorless bldc motor is quite an interesting challenge for microcontroller programming. You'd need the analogue input and 3 PWM channels. Probably 3 digital outputs, too to switch the polarity.
In other words: I'm taking apart a harddrive right now.

I am not saying that I want Red China to win (I actually want them to lose)

Huh? What are you talking about? Who do you think is at war there? Can't you just let the chinese people figure out their future themselves? Afaict we in the western countries, and possibly the whole world, benefit from their progress. And China obviously is changing it's political system.

No need to panic just because things change
