I can't comment about the FX5500, but I have the GeForce 8500GT running
dual-head. That has one VGA and one DVI connector.
Have you got the appropriate NVIDIA restricted drivers installed (and
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.

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
