Two X displays without screen blanking? (Monitor and TVout)

Hello,

I was wondering if anyone knew how to stop X from blanking the screen when switching displays. What I want to do is display one X screen on my monitor an another display on my TV using the TV out on my GeForce3 card. I am able to do this by executing 'startx' on one console and then 'startx -- :1 -screen tvout' on another console. The second startx goes to the TV out. Both X sessions launch no problem but I can view only one at a time, The other screen goes blank. Is there anyway to keep both screens visable? My main goal here is to have MythTV running on the second display while still be able to use the computer on the first X display.

Below are sections of my XFree config file that show the options used to get TVout working:

Section "Monitor"
Identifier "TV"
HorizSync 30-50
VertRefresh 60
EndSection

Section "Screen"
Identifier "tvout"
#Device "geforce"
Device "NVIDIA GeForce3 (generic)"
Monitor "TV"
DefaultDepth 24

Option "TVStandard" "NTSC"
Option "ConnectedMonitor" "TV"
Option "NoLogo" "on"

Subsection "Display"
Depth 24
Modes "800x600"
ViewPort 0 0
EndSubsection
EndSection

Hi,

the propietary nvidia-driver doesn't support dualview on GF3 cards (i suffer myself ;-)).
If you have a look in /var/log/XFree86.0.log there should be a line like "Dualview not supported".

On my card, the screen blanks even if I use nvtv :-/

Well I emerged nvtv and I have the option dualview checked off but the screen goes blank when I activate the TV out. Odd thing is when I deactivate the TVout half my screen stays blank... Wondering if the newest nvidia driver, that is currently masked, will enable dualview?
