yes i knew about nvidia drivers for FreeBSD...that's the reason i choose my notebook, instead of a ati driven laptop.
i tried with amd64 fbsd 8.1....same results...the only difference is that Xorg -configure now recognizes the nvidia0 on vgapci0 as "nvidia" and not just "nv".
Similar problem in this forum: http://forums.freebsd.org/showthread.php?t=3065
...the guy was luckier than me and eventually solved his problem
the weird fact is that asus provides 2 bios settings:
1.reserved vga0 on PCI:1:0:0 works with vesa
2.win7/vista: nvidia0 is recognized on PCI:1:0:0, vgapci1 on PCI:0:2:0 (internal intel graphic device). Both doesn't work, even with vesa driver...
...anyway...thanks for your time,
What I'm trying to do is to use one of the graphic adapter with a decent performance....don't need for switching technology...
