So the nvidia-settings app will create a config that can be saved. Move
that into place fails? Should be xorg.conf file .
Also try just X -configure to generate a nominally discovered xorg.conf
that can be tweaked. It sounds like your X is missing a lib but I don't
know what it is. It should span multiple monitors across multiple cards.
Hmm. Change my CRT0 to CRT2 and make certain you're in the first socket in
card 2.
