'ls -ltr /var/log/Xorg*' should display the logs in order, current or
most recent last.

Look at the current log or the most recent and pay attention to warnings
(WW) and errors (EE) - in some respects starting from the bottom and
working up can be useful.

Fairly important I think - in my experience the output will be sent to
one or other sockets according to the Busid defined in the config:
<example>
Section "Device"
Identifier "nVidia Corporation G80 [GeForce 8800 GTS]"
Boardname "nv"
Busid "PCI:2:0:0"
Driver "nvidia"
Screen 0
EndSection
</example>
So, does your card have two outputs and have you tried them both?
Which driver is used by default in /etc/X11/xorg.conf?
Finally, which motherboard do you have Rob?
