Thanks for the xorg.conf. It's gotten me farther along! I can see when I 
restart X the default char text "login:" appears (before X starts) on 
the TV -- in fact, it looks like it switches from Monitor to TV.  But, 
when X starts, it goes away on the TV and the Monitor is fine. I'm using 
a GeForce 4MX by BFG.

Any idea why? This is sent to a standard little tv. Perhaps the 
HorizSync could be changed? I have it at the standard 30-50. (I live in 
the use so I would imagine that VertRefresh should stay at 60)
