In another thread, a poster stated how to set up TwinView by manually adding a section (15-nvidia) to /etc/x11/xorg.conf.d.
I just installed the G03 driver from the nividia/SuSE repository through Yast and now have access to the nVidia X Server Settings panel. Version installed: 331.49-29.1.
Not that it should matter, the graphics card has a GeForce 8600 GT processor with dual dvi-i output.
Can one enable TwinView from the nVidia panel and if so how?
