probably an FAQ - g450 vs g400 tv out?

Hi,

I suspect this ought to be an FAQ, but I can't find anything definitive
easily...

I have a g450. I cannot get my tv to sync to the tvout if I attach the
primary crtc to that output (eg, taken from
http://www.rockhopper.dk/linux/hardware/graphics_cards.html:

#!/bin/bash
modprobe i2c-matroxfb
modprobe matroxfb_maven

matroxset -f /dev/fb1 -m 0
matroxset -f /dev/fb0 -m 0
matroxset -f /dev/fb0 -m 3

matroxset -o 1 1 # Sets the output to pal, ntsc users should use -o 1 2

# Set the resolution to 720x576
fbset -fb /dev/fb0 -left 18 -right 0 -upper 39 -lower 10 -hslen 46 \
-vslen 4 -xres 720 -yres 576 -vxres 720 -vyres 576 -depth 32 \
-laced false -bcast true

 - I just get rubbish).

That page is referring to a G400, not a G450 - is that my problem?
(obviously it would be nice to be able to get the goodies from the
primary crtc through the tv, rather than effectively having a dumb fb).

Cheers,

	David
