I use a dual display with my nouveau based laptop + DVI and it just
worked. The two panels are 1440x900 and 1680x1050. You should be able
to use the display option from the main menu or alternatively what
does running xrandr return from the command line? It should return the
two screens, what they're capable of running, and what they are
running at. You should be able to do something along the lines of
'xrandr --screen VGA-1 --auto --right-of VGA-0' to enable it. When you
removed the binary driver did you also remoove any of the xorg.conf
and binary kernel modules. The nouveau shouldn't need any xorg.conf so
that might be causing issues if  the other driver had one.
