X Windows dual head with ivtvdev

[Dan W. <dw...@mt...>]

In my system I have a 250, a 350, and the built-in ATI 9100IGP 
graphics chip.  I'd like to get X Windows to use the TV-Outs on both 
the 350 and the ATI at the same time.

If I turn on just the ATI (latest fglrx) or just ivtvdev in my 
xorg.conf file, it works fine. But if I set the main screen to be the 
ATI and position the 350 above it, I get a pretty bad lockup. X shows 
the mouse as an hourglass, stuck in the middle of the screen, and the 
keyboard no longer works. I have to SSH in from another machine to 
reboot it.

For my xorg.conf and Xorg.0.log, see this URL:

The syslog has a large number of DMA errors in it, which continue to 
get logged the longer I leave it in this state.

Here's the log from when the cards initialized. The 350 in question 
is the second card:
