I had the same problem with my desktop and I solved by disabling
secondary monitor (so the primary become Screen0) + restarting Xserver

nvidia-settings app

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





From you xorg.log it seems you have no nvidia-glx driver installed or
that it does not load due to a recent kernel update (I guess), have a
look to this how-to

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 ;-)
