I haven't since using the Mandriva xorg.conf. I have tried it from the 
menu entry and if xorg.conf doesn't exist it complains about the fact 
and does nothing. But with the nvidia driver active, and xorg.conf not 
existing or built with nvidia-xconfig, my monitor displays a floating 
dialog complaining about "Invalid Input" (this is the only thing 
displayed on the screen and is usually an indication of an invalid 
resolution/refresh rate combination as far as the monitor is concerned) 
so I can't issue nvidia-settings anyway.

regards,
Steve
