Dual Monitor with Xinerama

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?

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

I don't use Xinerama, but see here:

http://wiki.debian.org/NvidiaGraphicsDrivers

and read through this also

http://wiki.debian.org/XStrikeForce/HowToRandR12 perhaps in reverse order.

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

for Dual Monitor + Xinerama, right?
