Actually using the twinview options in Xorg and the nvidia driver the Fn+F8 no longer works (it does mention this somewhere in the nvidia driver README I seem to rememeber). Even so when I am in console mode (Fn+F8 does then work), the backlight is still on when I switch...
Thanks for your reply anyway... does anyone have a solution to this?
