[OpenIndiana-discuss] Selecting wrong video driver

[Alan Coopersmith]

/var/log/Xorg.0.log should have information on what config files the X server
read, what devices it actually found, and what decisions it made on which
driver to use for them.

It would have to be a very old motherboard to have an Intel graphics chip
that's not part of an Intel CPU - they merged them into a single unit years
ago.  But X won't assume an nvidia card based on the CPU, only on the PCI
device ids it finds that match nvidia's vendor id.
