Dear all,

I have just installed FreeBSD 7.1 Release on a machine with a GeForce
8500 GT (I think this is the card, but more about that later...) and
an LCD screen with a native resolution of 1680 x 1050.

Xorg works fine with the standard "nv" driver.  However, if I try to
install the x11/nvidia-driver (which should bring better graphic
performance, right?) I get a total system freeze when I start the X
server.

Here are the details of what I have done:

1) install x11/nvidia-driver
2) add nvidia_load="YES" to /boot/loader.conf
3) modify /etc/X11/xorg.conf by substituting "nvidia" to "nv" in the
Driver line.

At this point (after rebooting), if I start the X server with startx,
I get a black screen and the system *completely* hangs (neither
ctrl-alt-backspace, nor even ctrl-alt-delete work).  The only way to
get back the system is to power it off and on (which corrupts the
filesystem because it has not been properly dismounted).

I also looked at the xorg log file in:

  /var/log/Xorg.0.log

Interestingly it seems to detect the card  as a GeForce 9500 GT rather
than a 8500 GT (which makes me wonder whether I got the right info
from the vendor receipt):

  (--) Assigning device section with no busID to primary device
  (--) Chipset GeForce 9500 GT found

But this should not be an issue because in the same log file it says
that both GeForce 8500 GT and GeForce 9500 GT are supported by the
"nv" driver.

As for the monitor, the xorg log file says:

II) NV(0): Supported additional Video Mode:
(II) NV(0): clock: 146.2 MHz   Image Size:  473 x 296 mm
(II) NV(0): h_active: 1680  h_sync: 1784  h_sync_end 1960 h_blank_end

(II) NV(0): Supported additional Video Mode:

After this rather long post (I apologize), I have two simple questions:
1) is there a way to use the "nvidia" driver on this system?
2) is it worthwhile or does "nv" work just as well?

Thanks in advance for any help or suggestion.

best
