3.0 beta3: nvidia quadro fx 570m
greetings! just installed 3.0 beta3 on a thinkpad t61p with an nvidia quadro fx 570m video adapter. the internal display is fine, but i would also like to run an external cloned monitor. this doesn't seem to be an option with the available open source drivers. do i need to go to the proprietary nvidia module for this functionality? cheers! .pltk.
