Just a quick question about the above mode lines.  I'm here in Canada so 
I use the NTSC standard obviously.  My mode lines are the following:

        #1024x768 at 75Hz
        ModeLine "1024x768"     78.75 1024 1040 1136 1312 768 769 772

        #1024x768 at 70Hz
        ModeLine "1024x768"     75.00 1024 1048 1184 1328 768 771 777 
806 -hsyn$
        #800x600 at 85Hz
        ModeLine "800x600"      56.25 800 832 896 1048 600 601 604 631

The xorg log says its using this as my resolution:
(**) NVIDIA(0): Validated modes for display device TV-0:
(**) NVIDIA(0):      Mode "800x600": 40.0 MHz, 37.9 kHz, 60.3 Hz

It says that interlacing is available but I can't find any where where 
it says its actually using it.  Since I'm using a plain old (re 25 years 
old but still has a great picture) tv, I would think that an interlaced 
output would show the best picture.  How do I confirm that it is in fact 
using interlacing?
