Because I image the OS for the group of precisions we have here, I do 
not use the graphical tools. That's too much time to waste :-) .

I don't recall ever bothering with this tab. My reference of xorg.conf 
which works on my x86_64 RHEL based 490 is given below and it has given 
me a flawless dual setup on Quadro FX 3500 gear, all the way from Nvidia 
driver x86_64-1.0-8762 to the current version x86_64-100.14.11.

Of course, you need to modify the relevant XkbLayout statements to take 
the norwegian keyboard out. Hope that this helps.
