Make sure GSync II card is installed and connected to both graphics cards in correct order (primary, secondary)
Configure four outputs in Nvidia Settings tool as 2x2 array (dual Twin View with Xinerama)

xset +fp /usr/X11R6/lib/X11/fonts/100dpi 
xset +fp /usr/X11R6/lib/X11/fonts/75dpi 
xset fp rehash

Permanent solution: add the following lines to /etc/X11/xorg.conf as root (under the "Files" section):

FontPath "/usr/X11R6/lib/X11/fonts/100dpi"
FontPath "/usr/X11R6/lib/X11/fonts/75dpi"

Simage:

Download simage 1.6.1
'configure'
'vi libtool'
comment out the line starting with "predep_objects" to avoid multiple definition errors
'make'
'make install'

Coin3D:

Download Coin3D 2.5.0
'configure --disable-dl-simage'
make sure simage is listed to be statically linked, not at run-time
'vi Makefile'
in line starting with 'CC' add '-fPIC'
to avoid linker problem with libGL.so:
- 'su'
- mv /usr/lib/libGL.so /usr/lib/libGL.so.bak
- ln -s /usr/lib64/libGL.so /usr/lib/libGL.so
- exit
Download Zlib 1.2.3
- 'vi makefile'
- edit the line starting with 'CC': add -fPIC
'make'
copy libraries to extern_libs/lib64
Undo change to libGL.so:
- 'su'
- mv /usr/lib/libGL.so.bak /usr/lib/libGL.so
