I can't comment about the FX5500, but I have the GeForce 8500GT running
dual-head. That has one VGA and one DVI connector.


Key questions:
Have you got the appropriate NVIDIA restricted drivers installed (and
running)?

Is the X server using the proprietary nvidia driver or the open-source
one (nv)? You can tell because the proprietary driver will flash the
NVIDIA logo as X starts. The open-source driver may not support
non-vesa resolutions properly.

Are you using the nvidia-settings tool to configure X? That should
recognise the native resolutions of most monitors (especially newer
flat-panel models), and set up the X configuration appropriately.



I did not receive any
suggestions for getting my Nvidia card to work well after a couple of
previous posts, I've tried so many things from different posts and
suggesttions in my xorg.conf, but still no help. So, I am now asking for
any recommendation from anyone who knows of a card that would work well
in my environment.

All worked great with two LCD 17" monitors and my Matrox card for a long
time. One of those monitors died and I bought a new ASUS widescreen and
still struggling to get it to work well. I want to use the DVI input for
my new monitor with the 1440x900 resolution, can some suggest something
they know works well from experience?

If the 5500 has a DVI connector, it should successfully query the
monitor capabilities. The nvidia-settings tool, with the correct
restricted driver, should then set up the dual-head system.

Lots of further hints may turn up from googling 'FX5500 ubuntu
dual-head'

Thanks in advance!
