Down in the 'Screen' section, you need to have stuff like:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "ATSC-480-60p" "800x600" "640x480"
EndSubSection
EndSection
The label is arbitrary but it has to match your modeline
definition. Make sure that it's used in the /var/log/Xorg.0.log. Most
likely it'll say something like "Not using Modeline 'ATSC-480-60p' HSync
out of range' You'll need to redefine your monitors sync range to be
NTSC-friendly.... something like this is what mine says:
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell D1626HT"
DisplaySize 380 290
HorizSync 30.0 - 95.0
VertRefresh 50.0 - 160.0
...
The "HorizSync 30.0 - 95.0" needs to include 15.734kHz or X
will protect you from yourself. Change it to "15-64" or something...
Note that a VGA monitor won't sync that low (garbled picture), and
could possibly damage it... don't connect one when using that modeline if
worried.
