Its called xinerama. Google for a xinerama HOWTO. You will need to edit the /etc/X11/XF86Config-4 file so that it has entries for both cards & both monitors.
Is there a way to configure Knoppix to detect and use my 2nd video card for my 2nd monitor? Like a cheat code or something? Been out of the linux loop for a while and this is the first time I had to do this. My primary graphics card is a nVidia GeForce4 Ti 4200 128mb AGP and my secondary is a nVidia TNT2 m64 32mb PCI. Both are connected to generic monitors.
