Okay... so this one has me thinking. I have an old system with an onboard
i810 video controller, but was recently given a dead PC with a PCI NVIDIA
TNT2 which I was considering playing with, to grunt up 3D a little. Using
an additional video card in onboard setups is something I know is common.

When starting X, it appears to have an issue resolving the video adapter
against the onboard version, as X crashes with an error message about the
PCI bus not being available. I switched my Xconfig to "nv", and then to
"VESA", and although the console video was being displayed through the PCI
NVIDIA adapter, X didn't appear to be able to use it... It seemed to point
to a conflict somewhere.

There isn't any video being sent from the onboard VGA connector, and the
machine boots normally in text-only console display, so it's just X giving
me issues. What normally needs to be done to get this sort of thing
working?

Cheers

Tim

Have you tried setting the "BusID" parameter in your XF86Config file?
If that's pointing to your i810 (or absent), it's possible that X is
trying to use the wrong driver to drive the i810 and not seeing the TNT2
card at all. 'lspci' will tell you the bus address of the TNT2 and you
can then pass that in "BusID" parameter. (Note that there may be some
formatting differences between lspci's output and what goes into the
XFree86 file.)

Suggest you refer to the xinerama howto - it will make everything quite
clear.
