not sure my geforce3 did twin view
i'm not sure my geforce3 did twinview. i put in a newer nicer geforce4 from a different computer of mine and everything worked great. it was enabled automatically at boot time, and when X started, it seemed to do twinview just fine. not sure whether that had more to do with the X config or the card since it was outputting to both tv and monitor from the moment it booted. anyway, i don't care so much about twinview as getting the svideo out on my geforce3 working with X since ii ultimately just want to run mythtv or freevo with it.
