xorg.conf was created by nvidia-settings. What it is essentially doing is
creating a single desktop that extends across both monitors. I can drag
things across but there is an option to declare the TV as the primary
monitor and when I do that Myth starts on that monitor. I have been unable
to figure out how it does that. I looked at the code for starting myth on
startup and it isn't clear. I think I could modify the metamode line to
add the projector and place if off to the right of the TV with its native
resolution. I could then shutdown mythfrontend and launch it again targeted
to that part of the three monitor desktop that is the projector. If myth
responds to the
--geometry=WidthxHeight+Xoffset+Yoffset command I could use that. I don't
know if that works. It did not work for Chrome. Then I could create a
desktop icon that launched myth with the appropriate options. Right now
mythfrontend launches with a "--service" option
Here is what I am thinking:
Modify xorg.conf
Option "metamodes" "VGA-0: nvidia-auto-select +0+0, HDMI-0:
1920x1080 +1280+0,DVI-D-0: 1280x720 + 3200+0"
create desktop option
mythfrontend --service --geometry=1920x1080+3200+0
The only thing is I am not at all sure this will work. I guess I will have
to try it.
