Hi Doug,
thanks for the input but the driver for this card aren't available in the debian
packages yet, they're only available via nvidia's own download, including their
install script.

A belated thanks for the input (sorry for the long delay - started a new job and
everything got a bit hectic).

I now have colour, thanks to Andre, but things are no clearer on the glx front.

glxinfo initially segfaulted when I tried to run it.

So it seems that glx isn't working though. glxinfo outputs

Error: unable to open display (null)

and the Xorg log contains the failure:

This is with "load glx" commented out in the xorg.conf - needless to say I have
tried re-installing the nvidia driver, but not having changed anything else
deliberately, I am not surprised it had no effect.

Do you think X is mistakenly trying to load glx independently and failing, or
has it succeeded and glxinfo is just having problems of its own?
