Do I need to do this everytime I want to use an external monitor? Would
you mind sharing your modified xorg.conf after nvidia-settings updated
it?

no, you don't, it's safe to unplug the external monitor.
just take care of linux-image updates because you must repeat the compile+install steps to match nvidia-kernel-source version with your kernel

I didn't install nvidia-glx driver. AFAIK, it isn't something necessary
for Dual Monitor + Xinerama, right?

well, I don't know, I just followed the howto and it worked fine ;-)
