[mythtv-users] X over PVR-350

[sschaefer1 at woh.rr.com]

I think he may have been referring to having two PVR-350 cards in the same machine... meaning you wouldn't be able to have both television out ports running a X server simultaneously -- that was my take.

Personally, I have the PVR-350 running an X server for the MythTV frontend, and then I have a second X desktop running on my VGA card. (simultaneously)

I've seen a message where someone was using their X servers in congruance so that the television was the right half of their desktop... I've never tried it myself, but X should function fine with that -- probably be slow on the television side when screen updates occur...

I'm not sure where to get the most recent source code from. I ran into the 99% thing cause the driver was defaulting to /dev/fb0 instead of the /dev/fb2 that I had in the xorg.conf... John had me switch the lines to:

	#	Option "fbdev" "/dev/fb2"
		Option "ivtv" "/dev/fb2"

it works fine now.
